Abstract

Switching circuits having small power consumption and high response are constructed, when saturable reactor principles are employed. One such circuit is shown for performing the exclusive OR switching function. Two cores A and B have input windings N(A1) and N(B1) and output windings N(A2) and N(B2), respectively. The input windings N(A1) and N(B1) are series connected with a carrier input source I(S), while the output windings N(A2) and NB(2 )are connected series opposed to a load Z.

Exclusive OR Circuit

Switching circuits having small power consumption and high response are constructed, when saturable reactor principles are employed. One such circuit is shown for performing the exclusive OR switching function. Two cores A and B have input windings N(A1) and N(B1) and output windings N(A2) and N(B2), respectively. The input windings N(A1) and N(B1) are series connected with a carrier input source I(S), while the output windings N(A2) and NB(2 )are connected series opposed to a load Z.

The cores A and B are also provided with information input windings N(A3) and N(B3), respectively, each of which is serially connected to a battery E(dc), which biases each core to saturation. If either input winding N(A3) or N(B3) is energized by an input signal, the bias of the core is overcome and the incremental permeability is changed to allow transfer of the carrier signal to the load Z. If both the input windings N(A3) and N(B3) are energized by an input signal, the carrier signals transferred through both cores A and B are cancelled due to the opposing relationship of the output windings N(A2) and N(B2).
