Abstract

1,187,416. Impedance inverters. TELEFUNKEN PATENTVERWERTUNGSG.m.b.H. 6 June, 1967 [22 July, 1966], No. 26112/67. Heading H3W. An impedance inverter is formed from a resistance network and two high-gain amplifiers of the type having a low input impedance and a high output impedance, the parameters of the circuit being chosen in accordance with a number of equations set out in the claims. Fig. 4 shows one form of the circuit.
