Method for data compression and time-bandwidth product engineering

摘要

A method and apparatus for compression of digital and analog data utilizing an anamorphic spectrum transformation to warp an analog or digital signal to provide time-bandwidth compression after sampling is performed on the warped signal. The anamorphic spectrum transformation performs reallocating samples to assign more samples to fine features with high frequency waveform portions and fewer samples to coarse features with low frequency portions of the analog temporal signal, resulting in shorter record length and fewer number of samples.

1. A method of capturing a temporal waveform, comprising:
receiving a temporal waveform within a transformation stage of an electronic and/or optical circuit; wherein said temporal waveform comprises a temporal signal which is sampled at a sufficient rate to obtain desired signal information; and performing a transformation at said transformation stage for imparting a nonlinear warp onto the frequency spectrum of the waveform; wherein said transformation is performed in one or more domains selected from a group of domains consisting of analog, digital, optical, and electrical/radio/microwave frequency; outputting a compressed temporal waveform from the electronic and/or optical circuit.
