Topic 64: Wide-sense periodic, wide-sense cyclo-stationary, and quasi-stationary processes (PETARS, Chapter 8)This video considers a wider class of nonstationary processes that share some similarities with wide-sense periodic processes. Such nonstationary processes occur in systems where, for example,…
