Various analog to digital converters are available for this purpose. They are basically made up of operational amplifiers.
The other way is to convert the analog signal into samples. Then converting these samples into quantization levels. These quantization levels are then converted into 1s and 0s.
Analog data is an analog signal. There is no conversion required as the two names refer to the same type of signal.
Converters are available to convert digital signals to analog and from analog to digital.
There are quite a few ways to build a digital-to-analog converter (DAC or D/A). One of the more common circuits is the "R/2R" resistor ladder. It gets its name from its clever use of only two different resistor values, one twice the other. They are wired to give binary "weighting" to a set of parallel digital inputs. E.g, applying a 5V logic "high" to the most significant bit might cause 2.5V to appear on the output; applying a 5V "high" to the next significant bit will add 1.25V to the output, and so on. The number of resistors and parallel digital inputs determine the smallest voltage step and thus the resolution of the D/A.
Wikipedia has a good article titled "Resistor Ladder" that shows the circuit and how it works in more detail. Also see the article on Digital-to-Analog Converters for descriptions of other types of circuits. Each has advantages and disadvantages, e.g., one might be ideal for hi-fidelity audio in an inexpensive portable music player while another might provide the accuracy needed in a laboratory instrument.
All data in a computer is represented by bits. A bit can be either a 1 or a 0. Bits correspond with the amount of electrical charge in one RAM cell. A 1 means that a particular cell has a significant amount of charge, meaning it's "on". A 0 means that it has an insignificant charge or no charge at all, meaning it's "off". The state of a cell determines what electrical signal gets sent, making the computer do something. So, data is converted to electrical signals by means of bits that are either a 1 or a 0 that correspond with the amount of electrical charge in a RAM cell.
Digital data can exist in several forms. As a file, it will reside on a disc or in memory of some sort and as a stream, it will exist as a signal of some kind.
Therefore, digital signals are made up of digital data. They are simply data that are being moved from one location to another.
To convert file data to a digital signal, it is necessary for a process to be run that will take the data in a file and convert to a stream of data in the appropriate format.
With an Analog to Digital Converter (ADC).
An DAC convert digital signal to analog signal i.e Digital to Analog Converter. An ADC convert analog signal to digital signal i.e Analog to Digital Converter.
When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.
An analog-to-digital converter is a device which converts an infinite resolution analog signal to a finite resolution digital signal.
Because digital is in now
There is a device called a digital to analog converter (DAC).
The basic elements in digital signal processing are an analog to digital converter, digital signal processor, and digital to analog converter. This process can take an analog input signal, convert it to digital for processing and offer an analog output.
There are several devices called digital to analog converters for this purpose. 1s and 0s of the digital signal are used to represent the digital signal in analog form.
A UART does not convert an analog signal into a digital signal. It converts a serial digital signal into a parallel digital signal, and vice versa. The letters UART stand for Universal Asynchronous Receiver Transmitter. It is, fundamentally, a pair of shift registers.
transducer convert one energy to other energy .now in analog transducer it convert energy use of analog signal and digital it converts use og digital signal
Buy a new digital ready tv, get a digital receiver Sky or Freeview for your analogue tv
There are four possible combinations of encoding techniques -Digital data, digital signal -Digital data, analog signal -Analog data, digital signal -Analog data, analog signal
while conversion of analog signal to digital signal, we need to convert continuous analog signal to discrete signal. this can be done by dividing the analog signal into specific time slots. this process is known as sampling. there is a condition for sampling that can be given as follows. fs<=2fm
