Digit and shift Phase of Creating Signal Low Frequency-digit Apparatus of Measuring Phase

以单片机AT89C51为内核,利用查表方式实时送数,实现移相;键盘设置频率、电压、相位值,并可通过软件控制步进值,其可靠性强,硬件电路简单。

The system is taken microcomputer (AT89C51) for nucleus, and made use of the manner which look up the count and send it in install time. Then it moves the phase in install time. The system can display the install data by LCD.
