AIM
To introduce the basic concepts of Digital Communication in baseband and passband
domains and to give an exposure to error control coding techniques.
50
OBJECTIVES
 To study signal space representation of signals and discuss the process of
sampling, quantization and coding that are fundamental to the digital
transmission of analog signals.
 To understand baseband and bandpass signal transmission and reception
techniques.
 To learn error control coding which encompasses techniques for the encoding
and decoding of digital data streams for their reliable transmission over noisy
channels.
