摘要
论述一种新型水下运动目标信号源电路的设计与工程实现。工程中,选用单片机89C52和8279,复杂可编程逻辑器件(CPLD)将晶振频率分频,模拟电路产生噪声信号,开发了一个实用性强、功能扩展灵活、信号参数可调的低频信号源,经D/A转换和功率输出,送到换能器输出。其波形参数:频率、脉宽、周期、幅值均可键盘设置。
The new design and engineering realizing method of the underwater signal generator is discussed. By using single chip computer, crystal oscillator divided by CPLD（Complex Programmable Logic Device）, yawp signal produced by simulate circuit, a signal generator of low frequency is exploited. Through D/A transforming and power amplifying device the low frequency signal is sent to the transclucer to put out. The parameters such as frequency, pulse width, period, value can be set by the keyboard.
