摘　　要：总线与外围设备的接口一直是现代工业控制中最常用而又很重要的一项内容;FPGA由于其诸多优点也受到电路设计者的青睐,得到越来越多的应用。该调制器集成了这两方面的应用,将PC104总线上的数据通过FPGA进行数字调制,经放大滤波后产生连续、没有相位突变的2FSK信号,并输出到外围设备,起到数据传输和控制的作用。The interface between bus and its peripheral equipments is an universal and important content in modem industrial control. FPGA chips are applying more and more by the circuits designers. The modulator applies both of them,it obtains the data from PC104 bus,and modulates them in digital formats by a FPGA chip, continual 2FSK signal without phase saltation is gained after mag- nifying and filter circuits. This signal can be used to transmit data or control signals to the peripheral equipment.
