这事我用巴特沃斯模拟的方法设计的数字低通，高通，带通滤波器，其中只有一小段(I used this method to design analog Butterworth digital low pass, high pass, band pass filter, which only a short)

说明：  有关lfm的一些知识，希望对大家有一定的帮助(Some knowledge about FRFT transformation, we hope to have some help)

QPSK调制程序代码，绝对能用，大家一起分享(QPSK)

无限冲击响应滤波器 (IIR) 实现，涉及一个Butterworth低通滤波器，设计指标为：在通带内频率低于0.2π时，最大衰减小于1dB；在阻带内[0.3π, π]频率区间上，最小衰减要大于15dB (An infinite impulse response filter (IIR) implementation, involves a Butterworth low-pass filter design specifications as follows: in the passband frequencies below 0.2π, the maximum attenuation is less than 1dB in the stopband [0.3π, π] frequency interval , the minimum attenuation greater than 15dB )

本程序适用于将一段长语音文件分割为多个所需小段，长度大小可调节，写该蚕食即可(This procedure applies to a long voice file into small pieces more than the required length of the size can be adjusted, you can write the encroachment)
