Design of Signal Generator System Based on SCM
 
Abstract: The system is a digital signal generator based on single-chip microcomputer. AT89S52 is used as a control microcontroller core. The system is composed by digital/analog conversion(DAC0832), imply circuit(NE4558),button and LED lights . The low frequency signal generator can be controlled by buttons produce square wave, sine wave, triangular wave waveform, and displayed by LED. This paper introduces the basic principle of the peripheral hardware circuit and software part of the design content. This design implementation convenience, low cost, high stability, etc.
Key words: Single-chip Microcomputer;Signal Generator;D/ A
