The design of the digital function generator based on single-chip
Abstract：The article introduce the working principle of digital function generator and the design of hardware and system .The part of hardware make up of AT89C51 single chip , DAC0832 D / A converters, amplifiers and other auxiliary circuit. The principle of the system are in this aspects: The single-chip transfer the waveform code by read the data through the procedure, and the DAC0832 D / A converter the digital signal into an analog signal from the output of the single-chip, then show the signal amplification in the oscilloscope from the amplifier output. The part of the software programming language used the 51 single-chip assembly language. The system implement the digital signal function of the choice of output display with relatively simple hardware, include the advantage of a clearly, stability, reliable waveform display with, simply, simply to use, a certain degree of practicality.
Key words: digital function generator; DAC0832; 51 single-chip; wave; oscilloscope display
