Comparison between ADC and DAC?
An ADC, or analog to digital decoder, is used to "translate" analog signals into digital signals. An analog signal can take on any value, such as 0.1V, 0.5V, 4.12V, 5V and so on. A digital signal on the other hand can either be "high" or "low", 1 or 0. A computer can only work with digital signals, and therefore you need to convert an analog signal into a digital signal in order for the computer to be able to work with it. This is what you do when you record sounds or music. Sound is an analog signal and had to be converted with an ADC to a digital signal before it can be used in a compter or stored on a CD. A DAC, or digital to analog decoder is the oposite of the ADC. Here the digital signal is converted into an analog signal. This is what happens when you play music from a CD-plate. On a CD there are a number of holes, which each translates as a 0 or 1. These are read with a laser beam which is reflected back into a receiver whenever the laserbeam hits a hole. This then counts as a 1. When the disk is spinning it produces a stream of 1s and 0s, which togerther form a binary string, such as 00010111011101. The DAC then converts this value into a analogue signal, such as 1.1V, which is then used to power your speaker and produce audible sound.
What do you mean by analog signal and digital signal?
Digital signals have discrete encoded states that they switch between. They can only assume the defined encoded values. Errors can often be easily detected and sometimes corrected.Analog signals are continuous and change smoothly from one value to another, passing through all intermediate values. There is no way to identify errors.
What is the difference between an analog ic and a digital ic?
digitals ICs output either a high, +5v DC, or a low 0v. The outputs of digital ICs or on-off-on-on-off....etc. Analog ICs output waves in forms of sine, tri, basically anything but Square waves. Analog ICs usually used to regulate, amplify, filter, existing waves comming into its inputs. The digital ICs output a on-off signal based on what signals you give it. Analog ICs are not absolute, they are used in almost every design. Don't know where these other people got there info from, like they are based on PCB boards, wrong, they are based on silicon wafers they look exactly like digital ICs. Sure these Analog ICs may include some digital circuityry but their output is always analog and they are used in almost EVERY electronic/electrical device
What are the advantages of digital system over an analog system?
In general there is no direct advantage or disadvantage for either of the two technologies. There are various criterias that may result in an advantage for one of both in each specific design. All items below have to be considered during the design of (a part of) a device: * Is the electronic interfacing to analog or digital sensors / actuators / communication networks * What is the power budget * Is there a need for reconfiguring the design * What are the costs of the components * What are the skills of the available developers? Are they hardware or software minded? * What are the data throughput requirements? Those questions do influence the design. If this question refers to an already made design, the following items are important: * Digital systems which are processing analog data need to convert those signals. The conversion is the critical part. * Does the converter takes enough samples with a high enough resolution to be able to re-generate the original signal? * does the conversion use a lossy or loss-less compression technique? * Has the signal to be distributed over long distances, or to a lot of different places? Digital system easily integrate error detection and correction, where analog systems have more difficulties to do this. * Is a high quality required? You can see that it is strongly related to the target application, thus you have to make your own decision which is best in your situation. SPEED
What is the difference between power electronics and linear electronics?
Power electronics is study about controlling the power using electronics devices, Electronics is study about controlling the electrons flow&make amplification of electrons for required areas
Why is there less interference with digital signals than analog signals?
Analog signals require higher fidelity than digital signals because digital are either on or off while analog are continuous. A small difference in an analog signal is not detectable while it requires a large difference to turn on into off (digital signal). Error correction is easier with digital signals.
What is the transfer of digital or analog data using digital or analog signals?
The transfer of digital or analog data using digital or analog signals refers to the process of transmitting information from one device to another, either through digital signals or analog signals. Digital signals are electronic signals that represent binary data, while analog signals are continuous signals that represent continuous data. The method of transfer depends on the type of data being transmitted and the technology being used for the transfer. For example, digital data can be transferred using digital signals through a computer network, while analog data can be transferred using analog signals through a telephone line. Regardless of the method used, the goal of the transfer is to accurately transmit the information from one location to another.
Convert analog audio to digital audio?
An analog input voltage (or current) would be sent to device called an analog-to-digital converter (ADC or A/D). It is then converted to a discrete number and either processed or stored. In practical terms, you would have a device that has audio input connector(s) and digital output connector(s).
Why digital signals are more noise free than analog signals?
Digital signals are "forced" to be either 1 or 0, whereas analog signals are not. This means that a signal of 0.8 will be pushed to 1 in a digital signal and will remain 0.8 in an analog signal, and 0.2 will be 0 digital and 0.2 analog. This means that in order to overwhelm a digital signal the noise must do much more work to be effective. digital signal have only two states analog have infinite states therefore more susceptible to noise
How analog signals are different from digital signals?
An analog signal is a signal of varying amplitude. The signal can be: Light of different intensity Light of different colour Varying voltage like that produced by an MP3 player or Computer Soundboard. Varying levels of radiation We can easily compare the Analog signal with waves on the ocean. They go up and down and can vary in speed, size and intensity. Digital signals are very different. Digital signals are either on or off. In light, we either have light on, or we do not have light. Analog measuring is often a part of describing when a digital signal is a zero or a one. We measure for levels of light, or levels of voltage to define whether the signal is supposed to be interpreted as a zero or a one. This makes digital signals very resistant to background noise and they can travel very far with little or no degradation. Digital signals are very suitable for transferring information. This is actually what they are all about. Analog and digital signals go these days hand in hand when it comes to music. We transform an analog signal into its digital representation and by recording the digital information we do not get loss of information.
What are the advantages of using digital signals and why?
* Digital signals suffer less interferences than analogue signals. This means that when you listen to a digital signal you won't hear a hissing sound, as within digital signals regenerator circuits are used to clean "noisy" pulses. * Digital signals can be made very short so more pulses can be carried around each second, which means more information can be passed on.
What does a DVi-VGA cable do?
A DVI-D cable is a digital video display connector used in computers. It supports the same resolutions as VGA which has been the analog standard for many years. Digital signals do not suffer from timing errors that can sometimes reduce the clarity of an image delivered with VGA. Note that there are two other formats. DVI-A uses the DVI connector but it carries an analog signal identical to that of VGA connector. A DVI-I carries both digital and analog signals and therefore provides two video links within the same cable. Finally, DVI digital signals are compatible with HDMI video signals. DVI does not carry sound in either digital or analog video formats whereas HDMI supports sound within the same cable.
Can dedicated lines be either analog or digital?
Yes they can.
Can logic gates have analog input?
It's an ambiguous question, because technically all signals are analog. The short answer is no. By asserting they are logic gates, you are supposing digital logic criteria and analysis: high impedance input, nominal output impedance, the transistor's operating regions are either saturation or cutoff, and the I/O signals are analyzed in discrete steady-states. Digital signals are applied to logic gates as the distinction of "digital" establishes the above signal criteria and circuit operation.
What is the history of digital television?
The time it took to change analog television signals to all digital took about 25 years. It started around 1986 and many television stations had converted over to digital signal by the year 2010. Persons who owned analog televisions had to either buy a new digital television or use a converter box to get a clear signal.
What is the function of sensor on PLC system?
Sensors send incoming signals either digital or analog to PLC. There are a lot of types of sensors: inductive, capacitive, temperature, optical, etc.
How does music stored in a CD actually turn into sound in a stereo or computer?
The CD has tiny pits in a metal layer that are read by a LASER beam as binary 1s and 0s. These 1s and 0s are assembled into streams of digital samples of the sound along with error checking/correcting bits. The digital samples of the sound are fed through a digital to analog converter, which recreates the original electronic analog sound signals. These electronic analog sound signals are amplified and fed to either speakers or headphones so you can hear the recorded sounds.
