Abstract

Sound cards have become standard features of personal computers in the home, office and classroom. This paper demonstrates the usefulness of these inexpensive devices in the teaching of some of the basic and not so basic concepts of communications. These devices can be very effective in the explanation of amplitude, frequency and frequency multiplexed circuits, as well as modem handshake standards.
