基于Verilog的低频DDS电路系统设计

Design of Low Frequency DDS Circuit System Based on Verilog

提出一款应用在雷达中的主杂波跟踪系统和无线通信跳频系统中的DDS电路设计方案,实现现有合成频率快速变频。同时将ROM中存储的波形丰富其他波形:三角波、方波、锯齿波等,使该电路成为一个高低频信号发生器,产生任意信号。

This paper presents a DDS circuit design scheme,which is applied to the main clutter tracking system in radar and frequency hopping system in wireless communication to solve the problem of fast frequency conversion of synthetic frequency.At the same time,the waveforms stored in ROM are enriched with other waveforms,such as triangular wave,square wave and sawtooth wave,so that the circuit can become a high and low frequency signal generator.The circuit is of general significance in generating arbitrary signals.
