Abstract

Spectral warping (SW) is the digital signal processing (DSP) procedure of transforming an original digital sequence to a new one having special spectral properties: equally spaced samples of its DFT (Discrete Fourier Transform) are identical to the unequally-spaced frequency samples of DFT of the original sequence. The use of SW can open up new opportunities in test signal generation as well as in test response analysis for mixed signal circuits
