摘要
为满足大学物理实验与教学的需要,提出一种能演示两简谐振动合成的演示信号发生器的研制方法。采用高性价比的32位微处理器STM32F103RB控制两片数控单频信号发生芯片AD9835,同时输出双道高频率精度和高位相差精度的简谐振动演示信号。该发生器结合示波器能方便、直观地演示两简谐振动合成情况,可广泛用于大学物理及相关课程的演示实验和教学。
To meet the requirements of experiment and teaching about university physics,a performed signal generator,which may be used to show synthesis of two harmonic vibrations,was developed.With digital control,it used the 32-bit microcomputer STM32F103 RB to control two mono-frequent signal chips and the AD9835 to produce double-channel performed signal with high precision of frequency and phase difference. Combining with the oscilloscope,this signal generator is good and easy to demonstrate figures of two harmonic vibration syntheses visually. And it can be widely used in performing experiment and teaching of university physics and relative courses.
