SINGLE_POSITIVE_PULSE_GATES_SINE_WAVE_SIGNAL

Two transistors act as balanced shorting switch, eliminating pedestal effects that normally necessitate dual-polarity gate pulses for analog signal. Positive 10-V pulse saturates both transistors, thereby grounding both output terminals to give isolation from input signal. Analog signal being gated can be as low as 5-mv rms.-L. E. Frenzel, Jr., Gate Circuit Eliminates Pedestal Effects, Electronics, 37:15, p 77.
