目前,用高级语言在计算机上实现付里叶变换的快速算法程序已被普遍采用,但它的计算速度仍显得慢,当变换点数增多时,这个缺点就更为突出,本系统采用Z80汇编
At present, the fast algorithm program for implementing Fourier transform in high-level languages has been widely used, but its computational speed is still slow. When the number of transform points is increased, the disadvantage is even more conspicuous. The system uses the Z80 assembler
