摘要
采用一片8751单片机和两片DAC0832数模转换器组成数字式低频信号发生器,该装置采用键盘操作控制输出方波、正弦波、三角波,可用键盘方便地控制频率和幅值的变化,并将幅值和频率用4位十进制数通过LED数码显示出来.
The digital low frequency signal generator consists of a piece of 8751 monolithic computer and two piece of DAC0832 digital mould switching device. This equipment uses the keyboard operation to control output of the square wave, the sine wave and the triangular wave, the keyboard controls the frequency and amplitude change conveniently, and the amplitude and frequency is demonstrated out with four digit decimal system numbers by LED numerical code.
