摘要
选带频谱细化分析方法是数字信号处理中的一种重要分析方法。本文对以CZT算法实现选带频谱细化的计算及实现过程进行了分析。
The analytical method of high-resolution selected-band spectra is an imported one in digital signal processing. In this paper the calculat on and process of its realization by CZT algorithm are analyzed. It is proved that CZT-ZDFT is superior to normal ZFFT in amount of calculation, flexibility for use, accuracy of spectra and simplicity of realization.
