Design Of Signal Generator System Based On SCM

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 (UA741) ,button and LCD module.It can generate the square, triangle and sine wave, Through the keyboard input rapidly changing the shape and the frequency, wave to the purpose of human-computer interaction ,Meanwhile corresponding with LCD screen display name and frequency waveforms. The system can be used for a signal source in the low-frequency signal source. It is very practical.
