What is Digital Signal?

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

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

Simply, it is a signal that changes amplitude is discrete steps.

Digital Signals are obtained where discrete time signals are quantized and then coded.

Generally, digital signals are less subjected to deterioration during transmission.

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