Abstract

1,244,032. Gyrators. POST OFFICE. 4 Feb., 1969 [9 Feb., 1968; 22 Oct., 1968], Nos. 6533/68 and 50113/68. Heading H3U. A gyrator comprises a pair of differential amplifiers A1, A2 interconnected by resistors R1, R2, R3 and impedances Z1, Z2 one of which is resistive, the inverting input of A2 being connected to either input of A1 as indicated by the link BC. If resistor R3 is considered as an external load, the network constitutes a threeterminal network with an input terminal T1, an output terminal at the + input of A2 and a common terminal T2 (earth). In Fig. 4A, the load resistor R3 is constituted by a T network RA, RB, RC and is connected to two gyrators NA, NB each of which comprises a capacitor as the reactive impedance (Z1 or Z2). This arrangement is equivalent to an inductive T network, Fig. 4B (not shown). The network may be formed as an integrated circuit.
