摘要
针对目前信号发生器频率调整困难的缺点,提出了一种利用系数乘法器实现频率精密可调的新方法,并结合单片机、E^2PROM以及D/A电路,研制了一个信号频率在1~9999.9Hz范围内,按0.1Hz分辨率变化的多波形信号发生器。
The paper introduces an effective way, it has been used to made out a signal generator that frequency of signal can been precisely adjustable and signal waveform can been programmed by microprocessor, BCD coefficient multiplier, E2PROM and D/ A converter. The frequency of the signals can range from 1 to 9999.9Hz with the resolution being 0.1Hz.
