Abstract
This paper introduces a new technique of spectrum envelope estimation which can be executed in a parallel/pipelined VLSI system. This method is applied to time-varying waveforms. In order to evaluate better spectrum envelopes from waves, FFT or Gabor transform is used at the first stage, and then a self-organized network with a supervisor is applied in the second stage
