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
