摘要:
This invention provides for an enabling circuit that ensures a positive turn-on of semiconductor switches configured for the generation of a synthesized waveform, thereby eliminating misfiring of the switches due to electronic noise or logic malfunction. The circuit is configured to separately compare a sample waveform with a positive reference voltage and a negative reference voltage. The two results are directed to separate logic AND gates which have respective control signal inputs that regulate the formation of the positive and negative portion of a synthesized waveform. The output signals from the two AND gates connect to logic means to control the firing of the semiconductor switches.
