In the design of a communication system the challenge is to design the transmitter and the
receiver, which can encode/modulate the message signal, transmit it over the channel &
produce a satisfactory output at the receiver with an affordable cost. Digital Communication
is a solution for this.
In digital communication finite set of waveforms are closely matched to the characteristics
of the channel & are therefore more tolerant of channel impairments. By doing so, reliable
communication is established over the channel. In the selection of good waveforms over a
noisy channel, the design is influenced solely by the channel characteristics. However once
the appropriate set of waveforms for transmission over the channel has been selected, the
source information can be encoded into the channel waveforms & the efficient transmission of
information from the source to the user is ensured.
Digital Communication requires a considerable amount of electronic circuitry, which results
in increase in cost, but nowadays electronics are inexpensive due to availability of VLSI.
