Laboratory experiments for communications analysis

Abstract

This is a set of five laboratories designed to provide a working knowledge of the subjects covered in a course on the basics of communication theory. There are a wide range of topics covered. The concepts start with spectral anaysis of signals and continue with the sampling of those signals. Sampling at and above the Nyquist rate is demonstrated, as well as the inability to reconstruct an undersampled signal. Several signals are generated and analyzed. Modulation is accomplished on single and double-tone frequencies. Frequency- division multiplexed and time-division multiplexed signals are analyzed. Demodulation is accomplished through the use of low pass filters, envelope detectors, an AM radio and a phase locked loop. The equipment required for these laboratories is tabulated and recommendations are provided for implementation. Laboratory manual, data sheets and Solutions are also provided.
