labview 锁相放大器
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

我写一个免费的图象音频编码器,
i writing an free losless audio coder,
faster on old 486 than
flac or ape decoding on pentium 233 MHz !!!
the program working, and compression ratio is equal to flac / ape ...
On pentium 233 MHz flac decompress time is 26 sec of enya_.wav . ape is more than 45 sec... :)
approx 14 sec coding enya.wav with pkzip, and my routines not have completed.
My hope is 4 sec compression time, if completing,
and decompressing a 16 bit stereo 44100 Hz is real time on 80286 cpu !!!
PLEASE HELP ME !
i am an hungarian programmer, and i cannot wrtite in english perfectly.
i not have time for write code for
incoming 16 bit variable contents !
i want variable bit size putting into 8 bit foam.
the 16 bit variable containing e.g. 7 bit valuable data,
and 8 of this data must be storing into 8 bit datas.
(code need 24 .. 2 bit incoming packing into 8 bit data.)-i writing an free losless audio coder,
