The use of specialized multi-band stimuli for analog circuits testing

This paper presents the method of an analog functional testing which applies a non-periodic responses analyzing during the testing stage. The difference of energy levels for responses obtained to a pair of optimized stimuli was engaged to a circuit state determination. The proposed testing excitations have multi-band spectra of amplitude densities and they are specialized for investigation of assumed specifications. The amplitude densities of stimuli are optimized by means of evolutionary computations. Each population of evolutionary system consists of real numbered vectors which contain approximation coefficients for spectra of multi-band stimuli candidates.
