Abstract

PURPOSE:To enable to control the impedance with broad range, by connecting the impedance element predetermined to the first terminal and using the control circuit having predetermined transfer function which takes the signal of the first terminal as input. CONSTITUTION:The terminal 1 is connected to the element 10 and the control circuit 20 having arbitrary transfer function, and the terminal 2 is grounded. Arbitrary fixed or variable components such as resistors and capacitors can be used as the element 10, and the impedance of it is taken as Z. The input impedance of the circuit 20 is almost infinite, the output impedance is nearly zero and the transfer function is K. Taking the voltage at the terminal 1 as V and the current as i, V=iZ+vK, and accordingly, the impedance Z0 between the terminals 1 and 2 is Z0=v/i=Z/(1-K). Thus, by controlling the transfer function K, it can be applied to the signal having broad dynamic range signal with a simple constitution, and the two terminal impedance circuit greater for the variable range can be obtained.
