摘要
本文介绍了一种基于单片机和测量电压真有效值方案设计的智能数字交流毫伏表。它能精确测量任意波形的低频模拟周期信号并同时显示其有效值和分贝值。具有智能量程转换功能。
This paper introduces a kind of Intelligent Digital AC Millivoltmeter that is based on the Signal-chip Microcomputer and the design of voltage＇s real virtual value measuring. It not only can measure discretionary low-frequency analog signals exactly, but also can show their virtual values and decibels synchronously,which has the intelligent selectiveness of measure.
