This memorandum discusses basic concepts relating to analytic signal generation and envelope detection by discrete time methods. The calculation is made of the envelope of a real band pass signal using an analytic signal representation of the signal. Analytic signal representations are common in the development of radar, sonar, and more recently, geophysical signal processing techniques.
