The interlaced chirp Z transform

Abstract

In this paper we introduce the interlaced chirp Z transform (interlaced CZT). It is based on the computation of several carefully staggered chirp Z transforms (CZT) that are progressively interlaced to result in a spectrum that has denser frequency samples where needed. This simple modification of the CZT is shown to result in significant computational… (More)
