自己编写的一款可以进行双路PCM语音混频的程序，针对的是16位的PCM语音数据，经过验证，比常规的混音算法质量好许多，特别是进行多路混频时，重复调用该程序也可以达到比较满意的结果。-own section can be prepared for two-way voice PCM mixing procedures, The address is 16 PCM voice data, after verification, than conventional mixing algorithm many good quality, especially for multi-channel mixer, repeat the procedure call also will be more satisfied with the results.

labview 锁相放大器，基于相关检测原理设计了一种数字锁相放大器，重点研究了采样频率与相关运算结果的关系。发现参考信号为方波而采样频率与信号频率成一定关系时，系统相关运算存在固有误差。为减少该误差，首次将动态采样法引入数字锁相放大器设计中，运算发现动态采样的采样频率数越多，奇点产生的误差越少。基于LabVIEW 软件对所设计的检测系统进行了仿真 测试，测试结果表明该数字锁定放大器在信号幅度为5 V、噪声标准差小于等于50 时( SNR = －34． 04 dB) ，能有效地检测出频 率为500 kHz 以下的信号，系统检测结果与理论计算值的相对误差基本不超过2%。可以用于
