计算CDMA系统的误码率的最重要的函数，记得看哦，肯定有用(The most important function to calculate the error rate of the CDMA system, remember Kane, certainly useful)

语音信号的iir滤波器设计,从带有噪音的信号中提取原始声音.目前，MP3播放器一般功率放大器的工作频率范围就是这个范围。但是大部分有用的和可理解的信息的频率在200到3500Hz之间。所以我们可以在这个范围间滤波，达到使声音可理解的要求。现将数字滤波器的设计指标设为通带截止频率fb=600HZ,阻带频率fc=1200HZ,通带波纹Ap=1dB，阻带波纹As=40dB,要求确定H(z)。(design of the iir filter, get the original voice without noise)

power_transfosat.rar,功率电子领域matlab仿真文件，已经验证过，程序运行正常(power_transfosat.rar, Power electronics field matlab simulation file, has already been verified, the normal operating procedures)

Note that the energy-regenerative current is directly proportional to the motor speed and the braking torque. Hence, if the rider brakes his EV at a high speed, the surge current of the energy regeneration will damage the battery at the braking transient.
