Definitions

  • constant duty cycle means having an input coupled with said pulsing means and having an output, said duty cycle means responsive to said pulses for producing an output signal on the output thereof indicative of a first state for a predetermined precent of the time interval between the beginning of successive pulses from said pulsing means and indicative of a second state the remainder of said time interval between said pulses, the output of said duty cycle means coupled with the first input of said gate means;
  • said time multiplying means includes means for causing said variable time period of said gate inhibiting signal to be a predetermined multiple of the time period extending from the end of a pulse from said pulsing means until the output of said duty cycle circuit means changes from an output indicative of said first state to one indicative of said second state, no gate inhibiting signal being produced whenever said pulse from said pulsing means has a duration greater than the duration of an output signal indicative of said first state on the output of said constant duty cycle means.
