Digital Communication

Digital Communication:

Ø  Digital Communication is the one which uses digital signals for transmitting information between source and destination. Digital signal consists of discrete values rather than continuous values.

Ø  Power requirement in case of digital communication is less a compared to Analog communication. Since the bandwidth requirement in digital systems is more thus, they consume less power. 

Ø  Digital communication equipment’s are costly and digital signal require more bandwidth for transmission.

Ø  Digital signal is represented by square wave.

Ø  Digital signals are used in computers.
