frequency to voltage calculator
Convert frequency (Hz) to voltage using the sensor or circuit’s sensitivity factor. Ideal for F/V converters, signal processing, and instrumentation.

frequency to voltage sensor calculato
In order to change frequency to voltage, multiply the signal frequency (Hz) by sensitivity of the device (V/Hz). This provides a straight linear relation in the majority of F/V converters.

electrical signal converter
The Frequency to Voltage Calculator assists you in the process of changing the frequency of a signal, which is in units of hertz (Hz), to volts (V) using the conversion factor of your frequency-to-voltage circuit or sensor. Common uses of such conversion in electronics include in tachometers, audio processing and interpreting sensor data. The calculation of voltage can be done immediately as far as sensitivity (volts per hertz) is known. Take the example whereby a 0.01 volts per hertz sensor is utilized; this means that 200 hertz means 2 volts. The tool may be utilised by engineers, hobbyists and students in procedures related to frequency measurement, speed sensing and signal conditioning projects. It uses the direct proportion of frequency and voltage, so that accurate results may be obtained quickly without having to do math.
