A WEB BASED TRAINING MODULE FOR TEACHING DIGITAL COMMUNICATIONS
Abstract
An interactive module which simulates a digital
transmission link from one end to the other has been
designed. Using the module, a user may enter a short
audio/message signal using microphone of a PC, and
then follows processes on the signal at each stage of
the digital transmission link. The user can also analyze
the signal at every stage of the link, and compare the
performance of various modulation schemes used in
the link, and finally may see how the audio signal is
corrupted by noise in the transmission link. In this
way, from source point to destination point of the
signal, the user may study various stages such as
analog to digital conversion, analysis of effects of
Gaussian noise on the message signal.
