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. |
