摘要

In this work we present laboratory implementation of some experiments in the domain of Analog and Digital Communication. Usually different circuits are used for each experiment, and sometimes, ‘plug-in’ modules are used to connect and observe waveforms at different stages of the modulator. The single circuit proposed can be used to generate the three forms of amplitude modulation: standard amplitude modulation (DSB); double side band suppressed carrier (DSB-SC); single side band (SSB); and three forms of digital modulation like the amplitude shift keying (ASK); binary phase shift keying (BPSK); frequency shift keying (FSK). In addition, the same circuit is used to generate natural sampled waveform and the two-channel time division multiplexed waveform. We discuss the method and then present the experimental results.
