Pulse Generator

The apparatus produces a variety of pulse signals on output terminals 3 and 4 in response to the application of signals to either or both of input terminals 1 and 2 and under the control of manually operable switches 5 and 6.

With switches 5 and 6 in normal position as shown, signals applied to terminal 1 are passed through inverter 7, pulse amplifier 8, switch 6, variable delay line 9, OR circuit 10, and amplifier 11 to terminal 3. Signals applied to terminal 2 are passed through inverter 12, pulse amplifier 13, OR circuit 14, and pulse amplifiers 15 and 16 to terminal 4. Pulses arrive at terminals 3 and 4 in the order named. With switch 5 operated and switch 6 in normal position, terminal 1 input signals are re-routed to the input of blocking oscillator 17, which supplies pulses to terminal 3 via OR circuit 10 and pulse amplifier 11 so long as signals are present on terminal 1. When switch 5 is in normal position and switch 6 is operated, signals applied to terminal 1 are ORed at circuit 14 with signals supplied from terminal 2, and signals from both input terminals are passed to terminal 4 via pulse amplifiers 15 and 16.
