程控增益放大器

The Amplifer with Gain Controlled by Program

本文介绍几种程控增益放大器,并给出应用实例。此类放大器具有通用性强、软件编制容易,精度高等优点,可广泛运用于低频智能仪器及工业控制中。

This paper introduces several types of program controlled gain amplifers find gives some examples of their applications. These types of amplifiers have the characterristics of being universal, easy to program and high accuracy. They can be applied in low-frequency in.tellegent instruments and industry control systems.
