- 将4MHz的访波输入到ccc模块上，输出500Hz提供鸣叫声频。1kHz的方波经fen10模块进行十分频后为秒模块mian、分模块mina、时模块hour，提供时钟信号；用sst模块为整点报时提供控制信号，（当59 50\"、52\"、54\"、56\"、58\"时，q500输出为”1”，秒为00时qlk输出为”1”,这两个信号经过逻辑或门实现报时功能）；用sel模块提供数码管片选信号；用模块bbb将对应数码管信号送出需要的显示信号；用七段译码器dispa模块进行译码。 将4MHz的访波输入
DFilter
- This java applet is a demonstration of digital filters. You should hear a noise waveform when the applet starts up. If you get a message "Need java 2 for sound", then you should get the Java plug-in. The applet starts up with a low-pass filter.

- 用JAVA写的带通滤波代码，实现思路很简单，没有采用各种数字滤波的方法。而是通过傅里叶变换到频域，将要求外的频率均置0，再逆傅里叶变换得到的。效果还不错。-Written using JAVA bandpass filtering code to achieve the idea is very simple, without using a variety of digital filtering approach. But through the Fourier transform to t
