Input impedance derived from a transfer network

摘要

Circuitry for transforming a transfer function characteristic into a specified input impedance includes: a hybrid arrangement having input, transmit, receive and balance ports; and a two-port network connected from the transmit to receive ports of the hybrid. The relation between the input impedance at the input port to the network transfer function is expressible as a function of the actual impedance seen looking into the two-wire input port of the hybrid, and the desired impedance to be simulated.
