给出了数字信号处理课程设计的基本程序，包括采样、快速傅里叶变换、功率谱分析等。-Give a digital signal processing of the basic procedures for curriculum design, including sampling, fast Fourier transform, power spectrum analysis.

快速傅里叶变换是傅里叶变换的特例，本文档用汇编语言实现了快速傅里叶变换（即fft）-FFT is a particular case of DFT,The assembly realization of FFT is finished in this paper.

快速无损的傅里叶变换，效率最高的FFT之一，包含一维fft，二维fft（FK变换），以及三维fft（FKK变换）。-One of the most efficient FFT, contains one-dimensional fft transform two-dimensional fft (FK transform), and three-dimensional fft (FKK transform), a rapid non-d
