摘要：
In this work we describe the possibility of designing an analogue signal analyzer taking inspiration from biological and chemical information processing methodology present in the nature. The principal component of such a system is an adaptive-frequency Hopf oscillator. Using the proposed methodology it is possible to carry out Fourier as well as time-frequency analysis of a signal (similar to wavelet analysis) without changing the underlying circuit structure. This work may provide a route to a computationally superior and less power consuming next-generation signal processing system. Some open issues for making such an approach to practice are also discussed.
