A Solid-State Electronic Switch for Auditory Research
IEEE Transactions on Biomedical Engineering · 1965
A solid-state electronic switch is described. It is capable of switching audio signals (20 c/s to 100 kc) and producing rectangular, trapezoidal, or Gaussian envelopes. A fast switching circuit is used in conjunction with a Hall Multiplier. An external gate voltage controls the duration of the output envelope. The on-off ratio is 80 dB up to 50 kc. The switching transients are 60 dB below the output signal.
