Why do we compute the spectra?

Abstract
Mechanisms underlying biological phenomena are often understood on the basis of equivalent electric circuits. An effective way of probing a biological system is to measure a signal which is a reflection of the phenomena and to analyze it according to the conventional recipe, for instance, the spectrum analysis. In this paper the meaning of spectrum analysis of a biological signal is briefly discussed in connection with linear system identification. Wiener analysis of a non-linear system is also mentioned.
