摘　　要：叙述了预加重技术在低频信号处理中的应用 ,该方法可以大大加快应用系统的响应时间及提高系统的实时性 ,利用IIR和FIR数字滤波器实现预加重技术 。This paper deals with the application of pre-weight technique in the processing of the vibration signal of the low speed turbo-generator. This method can improve the response and the real-time quality of the applied systems. The pre-weight system designed by IIR and FIR digital filter can largely simplified the hardware design of the applied system.
