METHOD AND SYSTEM FOR INVERSE CHIRP-Z TRANSFORMATION

摘要

Provided are a method and a system for an inverse chirp-z transformation, and more particularly, a method and a system for an inverse chirp-z transformation having improved availability as compared to conventional Inverse Discrete Fourier Transform (IDFT) or Inverse Fast Fourier Transform (IFFT) because a start time of an output signal and an interval between samples are freely adjustable in obtaining a signal on a time domain by performing an inverse transformation for any spectrum signal on a frequency domain.
