摘要
The disclosure relates to apparatus for transducing time duration signals into digital form and concerns a scheme for preventing contact bounce noise in said signals from triggering the production of the control pulses needed for the transducing process. The scheme includes a one-shot multivibrator which produces an output pulse of longer duration than the bounce period whenever the signal reverts to its reference level, and apparatus which senses both said output pulse and the time duration signal and produces a control pulse only when the trailing edge of said output pulse occurs at a time when the signal is at its reference level.
