High resolution spectral analysis with arbitrary spectral centers and adjustable spectral resolutions
Abstract
A technique was needed to perform spectral analysis with arbitrary resolution bandwidths and with arbitrary band-center locations. A method was derived to realize band centers that are equally spaced on a log-frequency scale, and with bandwidths that vary proportionally with the band centers, or that vary as the square-root of the band centers.
