水下任意波形产生电路的设计与实现

Design and Realization of Arbitrary Underwater Waveform Generator

根据水下目标运动参数测试需要,提出一种新型任意波形生成电路的设计方法。该系统充分利用单片机和CPLD控制电路的功能,将欲设计的波形参数预存于E2PROM中;波形数据读出后,经D/A转换和功率放大输出。基于CPLD和波形数据预生成的设计方法,实用性强、功能扩展灵活、信号参数可调,实现了硬件电路的软件化设计,降低了成本;并可产生多种信号源波形。

The new design method of arbitrary underwater waveform generator is discussed. Based on the control of single-chip computer and CPLD logic circuit, the waveform is accessed by means of index in E2PROM. The needed waveform is obtained after it is D/A coverted and amplified. This design which based on above mentioned simplifies the circuit and reduces the cost of production.
