Converters: Period to Frequency

Circuits Designed by Dave Johnson, P.E. :

  • PULSE PERIOD TO VOLTAGE CONVERTER
    This is a test circuit converts a square wave input signal into a voltage. But, the voltage produced is proportional to the time between edges (period) of the signal, not the frequency. The range is from 100uS to to 10mS, which produces a voltage from 100mV to 10 volts. Other scale factors are also possible. The circuit is powered from single 15v supply and uses inexpensive parts. It is great when a signal's period instead of its frequency needs to be monitored.
