Abstract
A pyramid frequency analyzing technique is taught in which an input sampled temporal signal is convolved with a spatially localized, gradual rolloff kernel weighting function, which is subtracted from the input signal in each pyramid stage prior to the convolved signal having its sample density decimated and applied as an input to the next pyramid stage (rather than subsequent to the convolved signal having its sample density decimated as in a Burt Pyramid analyzer). In addition, a synthesizing technique is taught which provides additional high-frequency peaking in each stage thereof, not provided by a Burt Pyramid synthesizer.
