| 摘 要： | 介绍了一种键控式的采用单片机对高频函数发生电路进行程序控制的高频信号发生器的设计方案。此方案能产生方波、正弦波和三角波等信号;采用数字频率合成器,使输出信号频稳度和晶体振荡器的相当;并用键盘设置波形和频率,由LED显示。输出信号的频率分成1 MHz~16 MHz和8 kHz~999 kHz两挡。

| Abstract: | A kind of design method,using single chip computer to control the high-frequency signal generator to build a wide frequency band signal generator is introduced in detail.It can generate sine,triangle and rectangular waveforms.It also uses a frequency synthesizer to make the frequency as stable as a crystal oscillator.The selection of waveform and frequency are set by a keyboard and shown by LEDs.The frequency of the output signal is divided into two ranges: 1 MHz to 16.383 MHz,and 8 kHz to 999 kHz. |
