随着数字信号处理技术在各个领域中的迅速扩展,人们对用微机来构成数字信号处理装置的要求越来越强烈,为此我们利用汇编指令设计编写了一个数字信号处理专用的子程序包。它包含了常用的函数计算程序:FFT 快速傅里叶变换计算程序;自功率谱、互功率谱计算程序;自相关函数、互相关函数、卷积计算程序。最近为了满足更多用户的需求,特地在原程序包的基础上增加了HANNING 窗函数的计算程序,这是一个用于解决频谱分析中泄
With the rapid expansion of digital signal processing technology in various fields, people have become more and more strongly required to construct a digital signal processing device by using a microcomputer. For this reason, we write a subroutine package for digital signal processing using assembly instruction design. It contains commonly used function calculation program: FFT Fast Fourier Transform calculation program; self-power spectrum, mutual power spectrum calculation program; autocorrelation function, cross-correlation function, convolution calculation program. Recently in order to meet the needs of more users, specifically in the original package based on the increase of HANNING window function calculation program, which is a solution to the spectrum analysis of the vent
