# TC9400 Analog Division (Ratiometric Measurement)

A circuit which will divide one analog signal by another is one of the most difficult circuits to build. TC9400 voltage-to-frequency converter make it easy to build such circuit. Here is the block diagram of the system:

Two voltage-to-frequency (V/F) converters can do such division with ease. While the denominator forms the time base, the numerator is counted directly as a signal. [System’s block diagram source: Microchip Application Note]
