(1)设计低通、带通、高通数字滤波器； (2)可以对合成信号(含低频、中频、高频分量)、语音信号进行滤波； (3)通过GUI界面进行控制。-(1) design low pass, band pass, high pass digital filter (2) can be synthesized signal (including the low frequency, medium frequency, high frequency components), filtered s

通过对随机信号的处理，将其转换为带限信号，再将其通过不同阶数的带通滤波器，得到滤波后的信号。(By processing the random signal, it can be transformed to band limited signal, and then pass the bandpass filter with different orders to get the filtered signal.)
