The Design And Analysis Of An Analog Ratio Spectrum Circuit
Abstract
The ratio spectrum (RS) is a novel method for signal analysis that has been successfully demonstrated for speech recognition and coding applications. In this paper, an improved RS circuit with an adaptive tenth-order Butterworth low-pass filter has been designed. We also present the first convergence analysis of the ratio spectrum. We derive linearized convergence expressions for the RS and compare the theoretical predictions to circuit simulations.
