Definition for Digital Signals

Digital signals are discrete time signals generated by digital modulation. It is a signal where amplitude can have only given discrete values between defined limit.

Digital signals are discrete time signals generated by digital modulation. It is a signal where amplitude can have only given discrete values between defined limit. Simply, it is a signal that change amplitude is discrete steps.

Digital signals are obtained when discrete time signals are quantized and then coded. Generally, digital signals are less subjected to deterioration during transmission.

Digital signals are denoted by the square wave. The output of the digital computer is an example of the digital signal. The waveform of a digital signal is known as a digital waveform.
