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.

557 Makes Handy Voltage-to-time Converter - 02/01/01 EDN-Design
Ideas.....The circuit in Figure 1 is a simple, low-cost voltage-to-time
converter using ubiquitous 555 timer chip. You can use IC's
monostable multivibrator as a voltage-to-time converter by connecting
analog-voltage input to charging resistor, R, instead of
connecting R to VCC. With this modification,..... [Design Idea by J

Circuit converts pulse width to voltage - 25-Oct-01 Issue of
EDN The circuit in Figure 1 converts pulse information to a clean
dc voltage by the end of a single incoming pulse. In another technique,
an RC filter can convert a PWM signal to an averaged dc voltage, but
this method is slow in responding. Converting low-duty-cycle pulse
information is slower yet..... [Design Idea by James Mahoney, Linear
