Abstract

The two core gating circuit 1 is used in connection with a generator or amplifier 2, the output of which is determined by the state of magnetization in the respective cores 3 and 4 which preferably have identical square loop characteristics. Core 3 acts as a transformer whereas core 4 serves for voltage compensation. Information passes from the trigger input terminal 5 through the gate 1 to the output 6, if the core 3 is in its 1 binary state. However, no information passes if the core 3 is in its 0 binary state.

Magnetic Gating Circuit

The two core gating circuit 1 is used in connection with a generator or amplifier 2, the output of which is determined by the state of magnetization in the respective cores 3 and 4 which preferably have identical square loop characteristics. Core 3 acts as a transformer whereas core 4 serves for voltage compensation. Information passes from the trigger input terminal 5 through the gate 1 to the output 6, if the core 3 is in its 1 binary state. However, no information passes if the core 3 is in its 0 binary state.

A start pulse at terminal 7 sets core 3 to its 1 state and core 4 Into its 0 state. A stop pulse at terminal 8 sets core 3 into its 0 state and core 4 into its 1 state. In the stop condition, if a trigger pulse is applied at terminal 5, the core 3 remains in its 0 state and only.a very small voltage, which can be disregarded, is induced in the input winding 9 of the generator. In the start condition, however, a trigger pulse at terminal 5 switches core 3 from its 1 state to its 0 state to induce a voltage in the input winding 9. A delayed reset pulse derived from the output of the generator 2 on a line 10 automatically resets the core 3 to its 1 state thus permitting the generator to continue delivering output pulses every time a trigger pulse is applied to terminal 5.

The lower core 4 is provided for introducing a compensating voltage into the input winding 9 of the generator every time the transformer core 3 is switched by apply...
