approach, you can systematically look at the structure of
complex signals. The building block approach allows for
the testing of electronic circuits under very controlled
conditions. This technique also enables precise control of
signal bandwidth and spectral content.
The building block approach can be used to produce
a variety of complex wave forms including AM and SSB. It
can be used to inject noise into a signal and test the
performance of various types of detectors.
These simulation techniques can be looked at by the
technician and the technical educator as tools for testing,
comparing, and explaining various circuits. NV
