A method to perform the sampling step of application specific processing for signal processing, primarily digital signal processing of signals derived directly from measurement of a one dimensional or multi-dimensional physical quantity or after processing the physical signal into an N dimensional derived signal. The method extracts information from the signal at discrete points and the sampled values are fed into rigorous mathematically provable correct algorithms, to perform nonuniform sampling. The sampled values may be used to calculate the coefficients of a Fourier or other transform of the signal.
