V – F converter

Published on Jul 23 2015 // Detection circuit

The V - F converter circuit converts the input voltage to a desired frequency.

V-F converter circuit:

The V-F converter circuit converts the given Voltage to Frequency. From the leads of the IC 741, the input voltages are given to the two pins, 2 and 3. The IC converts the voltage to the required frequency, using the formula given below in the circuit. The 555 IC converts the frequency and it is heard as an audio voice in the speaker connected in the 2 pin of the IC.
