多功能函数发生器的设计

摘要

函数发生器又称波形发生器,是一种常用的信号源。目前国内生产的函数发生器大部分是利用分立元件组成的,靠手动来转换量程,其体积大,可靠性、准确度都比较差,不能满足科研、生产的要求。随着大规模集成电路和单片机的迅速发展,这就提供了仪器更新换代的可能性。近年来我国利用大规模集成电路ICL8038组成的函数发生器,进行一系列调试和实地测试,结果表明完全可以取代以往的模拟电路。利用ICL8038芯片和外接少量的元器件,就能制成质量技术先进、结构轻巧、价格低廉、用途广泛的多功能函数发生器。在上述基础上,如利用单片机进行控制,即成为多功能智能函数发生器,它既能产生各种波形,又能以数字形式显示新产生波形的频率和幅值,且能程控。利用单片机的运算和存储功能,可以编制一系列以提高准确度,增加功能的软件。这对函数发生器准确度的提高、体积的缩小和功能的加强有着重大的影响。本仪器由下列几部分组成:函数发生器,真有效值转换电路,A/D和D/A转换电路,单片机最小系统,显示键盘和控制电路。

The design of multi-function generator

Abstract

Waveform generator function generator is also called, is a common signal source. At present, the majority of production is the use of function generator composed of discrete components, to rely on manual conversion range, the size, reliability, accuracy than the poor, can not meet the scientific research and production. With the large-scale integrated circuits and the rapid development of single-chip, which provides the possibility of replacement equipment. In recent years, China's use of large-scale integrated circuits composed of ICL8038 function generator, carry out a series of debugging and field test results show that can replace the analog circuits. ICL8038 chip and use a small amount of external components, advanced technology can be made of the quality, structure, lightweight, inexpensive, uses a wide range of multi-purpose function generator. On that basis, such as the use of single-chip control, th
