模拟乘法器是模拟电路的重要分支.它是功能电路和非线性组件.象集成运放一样,其通用性很强.它不仅能完成乘、除、平方、平方根等模拟运算,完成正弦、余弦、幂级数和多项式等各种函数发生器,而且还广泛应用于通信工程、自动控制系统、电气测量设备、化学分析等许多技术领域.仅在电气工程中的应用而言,它能被用来作成低失真正弦波和正交振荡器,压控重复频率的方波和三角波发生器及各种波形变换器;亦可作成压控带宽的一阶和二阶有源滤波器,压控增益的宽带放大器;可实现普通振幅调制,
Analog multiplier is an important branch of the analog circuit. It is a functional circuit and nonlinear components. Like the integrated op amp, its versatility. It can not only complete the multiplication, division, square root and other analog computing, to complete the sine, cosine , Power series and polynomials, but also widely used in many technical fields such as communication engineering, automatic control system, electrical measuring equipment, chemical analysis, etc. It can only be used in electrical engineering applications To make low-distortion sine and quadrature oscillators, voltage-controlled square wave and triangular wave repetition frequency generator and a variety of waveform converters; can also be made of voltage-controlled bandwidth of the first and second-order active filter, voltage-controlled gain Broadband amplifier; can achieve ordinary amplitude modulation,
