Claim Text:
1. A method for digital signal processing, implemented on a computer having one or more processors and one or more memory devices, the method comprising: receiving a digital waveform signal from data storage or from conversion of a physical analog signal received from an analog source or captured by a physical analog device; determining two or more measuring matrices from the digital waveform, each matrix consisting of a plurality of cells, each cell representing a corresponding time slice and frequency bin and having an amplitude corresponding to the signal energy for that frequency bin and time slice; identifying various types of maximum cells in each measuring matrices based on their having a local maximum amplitude; identifying correlated maxima as maximum cells from multiple measuring matrices that coincide in time and frequency or multiplies type of maxima or a combination of measuring matrices; constructing a correlated maxima matrix that indicates the correlated maxima; identifying, in the correlated maxima matrix, at least one of the following domain relationships of the correlated maxima: time domain, frequency domain, harmonic domain, amplitude domain, partial chain domain, repeating domain, memory domain, non-random domain; constructing a domain matrix showing the identified domain relationship; and outputting the domain matrix to thereby reveal information associated with the input signal, wherein outputting includes at least one of storing, transmitting and/or displaying the domain matrix, wherein the receiving, determining, identifying maximum cells identifying correlated maxima, constructing and outputting are performed by one or more processors.
