What is convert analog to digital convert?
An analog-to-digital converter is a device which converts an infinite resolution analog signal to a finite resolution digital signal.
How are digital aerials different from analog ones?
Digital aerials get a better quality of picture than do analog aerials. in addition, digital aerials can get high definition signals over the air,where analog aerials cannot.
Differentiate between an analog and a digital electromagnetic signal?
1. Digital Signal is non-continuous signal where as analog is continuous signal 2. Digital signal contain only two value that is 0 or 1,or high or low where as analog contain all the values in it's time interval 3.Chance of attenuation in analog is more then digital signal
What is the difference between analog links and digital links?
1.analog link have low SNR ratio whereas digital have high; 2.multichannel capabilities require high linearity optics ,whereas digital have good; 3.environment factors : moderate for AM and excellent for FM ,digital link have excellent
Analysis of digital and analog circuit?
Analog circuit continuous uses the time voltage and currents while digital circuits are sometimes called the on/off and high/low control of voltage in circuits.
Is anti aliasing filter analog or digital?
It must be an analog filter. The high frequencies must be attenuated before any digital sampling takes place, to ensure that these high frequencies are not sampled as false signals. See the related link.
Is digital electronics is the best or analog electronics?
They have their own merits and demerits you can't say digital electronics is best because in real world everything is available in analog quantity. Although Digital electronics is more reliable in comparison of analog because there is very high reliability in the sense (effect of noise) and correction of errors that occurred during transmission of digital signal, while this is not possible in analog communication.
Why it is generly true that a digital signal required high bandwidth than analog signal?
A: Analogue signal Direct voltage that varies in the low spectrum of frequency on digital signal the information is deciphered in micro seconds therefore the frequency must be hi the higher the better.
Why same junction box is not used for digital and analog signals?
Signal crosstalk. Most specifically is high speed digital switching noise being picked up by analog circuits and upsetting their operation.
Digital signals can send much more of this than analog?
Analog signals can't be compressed as well as a digital signal can. To transmit an image on analog television, every pixel is included in the signal. A standard NTSC screen includes 525 lines of 720 pixels, for a total of 378,000 pixels per frame. That's a lot, but it fits into the 6MHz bandwidth of a television channel. Japanese HDTV takes 20 MHz of bandwidth to send pictures with over 675,000 pixels. That's over two times as much signal to send a high definition picture and higher quality sound, but no other data.
What's the difference between digital, regular, and HD cable?
Traditional cable is analog, which requires more bandwidth per channel. Usually you need a cable box to receive Digital cable which shall also include High Definition (720p) channels if you subscribe to them. You can also receive local HD channels with an antenna, but you'll need a new television that can receive digital channels or a digital converter box.
Difference between analog simulator and digital simulator?
The big difference is inputs and outputs. Digital ICs expect high/low true/false inputs and outputs. Analog ICs take any inputs, and produce outputs of any level. For example, an audio amplifier is an analog IC. It takes an analog input (sound), and produces an analog output (louder sound). A ripple counter is an example of a digital IC. It takes a digital input (clock pulses), and produces a number of digital outputs (the digital outputs of the flip flops, collectively representing a number in binary).
