Topic 71: Introduction to System Response to Random Signals (PETARS, Chapter 10)

This Topic introduces the concept of calculating the stochastic process at the output of a known deterministic system, given a stochastic process at the input of the system. This concept is…

Topic 70: Cross-Power and Complex Spectral Densities (PETARS, Chapter 9)

This Topic extends the definition of the power-spectral density in two ways. First, it considers the cross-power spectral density (CPSD) for considering the spectral characteristics of two-jointly…

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,…
