此程序实现无线信标定位，GPS产生的信号经过（7，4）汉明码编码后发送，接收端解码得到发送端坐标。程序分为发射和接收2部分，在Keil C下编译实现。-This procedure positioning wireless beacons, GPS signal generated by (7,4) hamming code is encoded to send, receive decoding client coordinates to be the sending end. Transmitting and receiving procedures are divided into 2 parts of the Keil C compiler under implementation.

在有线电视中实现程控有源滤波器设计。为了充分利用设备和传输线,需要一种具有频率选择的网络―滤波器,将同一线 路上不同的信号分开,在电视机中也需要不同的滤波器(即选择有用信号,抑制无用信号) 。下面利用8051 单片机与12 位分辨率的DAC1208 数模转换芯片相结合的系统实现时间常数可程控有源滤波器设计,阐述了硬件结构与软件设计-In cable television in the realization of program-controlled active filter design. In order to make full use of equipment and transmission lines, the need for a frequency selective network- filter, the same lines separate different signal in the TV also requires a different filter (ie, choice of useful signals and suppress unwanted signals). Following the use of 8051 and 12-bit resolution digital-to-analog converter DAC1208 chip combining system time constant can be program-controlled active filter design, the hardware structure and software design
