摘　　要：利用开关电容滤波器的特性构造了一个小波函数发生器，它能够方便地产生不同尺度下的小波信号波形。文中给出了一个具体的实现方案，并论证了随着样点数的增加和样点间隔的减小可以使所获得的波形与真正的波形间的误差足够小。A wavelet function generator making u se of the characteristics of switched capacitor filter is constructed,it can produce anveniently the waveforms of wavelet signals in different scales.A concrete practical scheme is also proposed.The mean square error between practical signal and theoretical signal can be made as small as possible so long as the number of samples is large enough and sample duration is small enough.
