  • Abstract
    The chirp Z-transform is used in the Wigner distribution for high resolution spectrum analysis. It has the capability to zoom onto the area of the signal of interest, which makes it a very useful spectral analysis tool for analyzing nonstationary time-varying signals. This capability results in a more reliable and accurate spectral analysis on the time-frequency plane
