Handout 15: Describing functions, Introduction Eric Feron March 31, 2004 General Philosophy General reponse of arbitrary nonlinear systems is somewhat complicated. We usually know the systems we work with. Work with finite families of 'most likely

Handout 18: Dual-input describing functions Eric Feron April 5,2004 Dual-input describing functions are for mixed signals(sinusoid small constant signal) Approximating non-constant signals with constant ones
