摘要
A/D转换是一种将模拟量转化为数字量的过程。二进制虽然理论上很容易理解,但实际上不易形成明确的概念,为了让初学者快速明确这一概念,利用LabVIEW编程模拟PIC单片机A/D转换的原理和结构,依据逐次比较法原理编制了A/D转换程序,并演示了程序执行结果,快速建立了模/数概念。
A/D conversion is a kind of process which converts analog value into digital Data. The binary system is difficult to form a clear concept for beginners in fact though easily understood. The A/D conversion program has been developed based on the method of successive comparison in order to make the beginners understand the theory quickly. The principle and structure of programming of LabVIEW simulating A/D conversion of PIC are introduced, the results of procedures implementation are demonstrated and the A/ D conversion concept is rapidly established.
