RATIOMETRIC MEASUREMENT (ANALOG DIVISION) One of the most difficult circuits to build is one which will divide one analog signal by another.

Two voltage-to-frequency (V/F) converters can do such division with ease.

The numerator is counted directly as a signal, while the denominator forms the time base.
