An alternate approach to the laboratory implementation of communication experiments

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.
