There is a device called a digital to analog converter (DAC).
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
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
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
There are four possible combinations of encoding techniques -Digital data, digital signal -Digital data, analog signal -Analog data, digital signal -Analog data, analog signal
Modem in fact acts as an interpreter. When computer exchanges datas with other computers in internet,it has to take the assistance of telephone. But computer understands digital signal whereas telephone analog signal. For making reconciliation between the two requires one interpreter who can convert analog to digital and digital to analog. Modem's activity is to convert analog signal from telephone to digital understood by computer and vice verse.
