| 摘 要： | 仪器由AT89C55单片机进行控制,通过键盘、LCD显示模块进行人机对话,完成波形选择、频段选择,频率、幅度输出控制。由MAX038产生正弦波、方波、三角波,其波形选择由单片机进行控制;频段选择由五档组成,可通过旋扭开关完成;频率由单片机输出数据经D/A转换后控制MAX038;幅度由单片机输出数据经D/A转换后改变放大器负反馈深度来实现输出信号幅度的变化。

| Abstract: | The instrument was controlled by AT89C55 single chip with the execution of manmachine dialogue via keyboard and LCD display module to complete output of controlling as to waveform option , frequency band potation, frequency and magnitude. Generation of sine wave, square wave, triangular wave via MAX038, the waveform option was controlled by single chip. Frequency band option was composed by five modules, completed via rotary knob switch. The frec/uency output data via single chip with the transference from D/A to control MAX038. Magnitude＇s data output via single chip with the transference of D/A of amplifier to realize variation of signal magnitude. changed negative tickling depth |
