what are the characters of digital signal
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.
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.
A digital signal is actually a complex signal. Consider the horizontal part of a digital signal as a component with 0 frequency and the vertical part of the signal as the component of infinite frequency. Also, consider the change from the horizontal to vertical as all the frequencies. Then we can claim that a digital signal is complex signal with frequencies from 0 to infinite.A digital signal is a composite analog signal with an infinite bandwidth.
we can do analog signal processing also but it is very expensive as comparing with digital signal processing that's why we generally choose the digital signal processing.DSP allows programmable operations.But we cannot do in ASP.
we have to do sampling in dsp because in dsp we have to convert all in analog signal in digital form so for converting into digital signal first we have to convert continuous tome signal into discrete time signal....so we use samplin in dsp...

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.
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.
There are four possible combinations of encoding techniques -Digital data, digital signal -Digital data, analog signal -Analog data, digital signal -Analog data, analog signal
The signal sent to the TV must be a digital signal as well.

Demodulation the opposite is Modulation And when you put them together you get MODEM Modulation/Demodulation = MODEM
Because digital is in now
