Abstract

Laboratory implementation of analog and digital communication experiments is presented in this work. The electronic circuit and the observed results for experiments such as: AM, DSB-SC, SSB, PAM, natural sampling, flat top sampling, sample and hold, ASK, BPSK, FSK, QPSK, PAM-TDM, is implemented using two ICs LF 398 and LM 741 as against conventional transistor based methods. In addition all these experiments have a combination of the `real´ circuit with `virtual´ instruments using the LabVIEW platform. The circuits as well as the combination of real and virtual are novel.
