摘要
电子设备发展日趋小型化、智能化，应用串行 Ａ／Ｄ转换器 ＴＬＣ５４９及ＭＣＵ ＡＴ２０５１设计的交流有效值测量装置，克服了一般便携式仪表测量有效值时的误差，易于实现通道增益修正和零漂的补偿，具有很高的性能价格比。
With the up-to-date trend of miniaturization and intelligentizing in electronic instruments,we design an AC RMS measuring instrument using serial A/D convertor TLC549 and MCU AT2051,with such advantages as getting rid of errors found in genera[ portable instrument measuring, easy gain modification and drift compensating and high performance/price ratio.
