内容： *红外测试程序，用单片机通过发射管发射38K的调制频率码，由一体化接收并解码由发光管显示。 *正常情况下，由于反射和高灵敏度接收，LED4（P1.3)一直闪烁，可以用黑色纸片完全遮挡接收头使 *之不能接收到发射管的信号，这是LED4熄灭。说明功能性正常 -Content:* IR test program, launched with the microcontroller through the launch tube of the modulation frequency of 38K code, by the integration to receive and decode from the LED display.* Under normal circumstances, due to reflection and high-sensitivity receiver, LED4 (P1.3) has been flickering, you can completely block the black pieces of paper to make* that they are not receiving the first emission control signal is received, it is LED4 out. Note the normal functional

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
