基于单片机的正弦波发生器的设计

Design of sine wave generator based on single chip microcomputer

正弦波发生器是一种可以产生各种函数的波形仪器,可以被用于科研、教学和生产实践等领域.正弦波发生器主要以单片机为设计基础,由硬件和软件两部分组成,软件系统通过Proteus和代码编写仿真产生,而硬件系统则由运算放大、积分、D/A转换电路和键盘显示等模块组成.以单片机正弦波发生器设计研究为基础,在正弦波的频率和幅度上均可进行调整,使得该发生器在设备检测和电路实验中广泛应用.

The sine wave generator is a kind of waveform instrument can produce various functions,can be used in the field of scientific research,teaching and production practice,etc..Sine wave generator mainly with single chip microcomputer as the design basis,is composed of two parts,hardware and software,system software by Proteus and code write simulation,and hardware system consists of an operational amplifier,integral,D/a conversion circuit and a keyboard display module.In this paper,the sine wave generator for design and research,in the sine wave frequency and amplitude can be adjusted,so that the generator in the equipment testing and circuit experiments are widely used.
