摘要
论述了采用两片乘法数模变换器把输入的数字码变换成电阻和电抗的简单而有效的电路 ,该电路实现的功能等效为对端口处等效电阻抗的数字编程 ,具有分辨力高的特点。此电路可用于动态皮肤阻抗模拟器、可编程滤波器、信号发生器、数字测量电桥。
Instroduces a simple and efficient circuit, it adopts two MDACs which transform digital code input into resistance and reactance The circu it with high resolution is equivalent to digital programming impedance at the port The circuit can be used in dynamic skin impedance stimulation, programmmable filter, signal generator, digital meterage electric bridge, impedance criterion
