摘要：本篇报告基于实物设计:一个X-Y信号生成和图形显示装置目的,采用使通用示波器工作于X-Y的方法,结合外加的正弦波频率为1 kHz,电压的峰峰值为2 V,可以实现移项等一系列功能的实验。可以得出移相电路模块主要通过单片机stc89c52控制模拟开关电磁继电器进行选择实现了移相步进特定可调;运放模块主要运用LM324芯片,该芯片具有高速运作的特点。首先移项0°利用的是典型的电压跟随器、移项180°利用的是反相器,然后其他特定角度利用不同的移项模块进行测试的结论。
This report is based on physical design: an X-Y signal generation and graphics display device.By using the method of making the general oscilloscope work on X-Y,combined with the additional sinusoidal frequency of 1 kHz and the peak value of voltage of 2 V,a series of functional experiments such as item shifting can be realized. It can be concluded that the phase-shifting circuit module is mainly selected by the analog switch electromagnetic relay controlled by the single chip STC89 C52 to realize the specific adjustable phase-shifting step;the operational amplifier module mainly uses the LM324 chip,which has the characteristics of high-speed operation. Firstly,the typical voltage follower and the inverter are used for the shift term 0,and then the conclusion of the test is made by using different shift term modules from other specific angles.
