[Abstract] The system is a digital signal generator based on single chip computer. At89s52 is used as a control microcontroller core. The system is composed by digital/analog conversion(DAC0832), regulator circuit(MC1403), imply circuit (LM324) ,button and LED lights .It can generate the square, triangle and sine wave, with LED display. The system can be used for a signal source in the low-frequency signal source. It is very practical.
