Voltage-to-Frequency / Frequency-to-Voltage ConvertersVoltage-to-frequency (V/F) and frequency-to-voltage (F/V) converters are electronic devices that are used to convert between voltage and frequency signals. These devices are commonly used in a variety of applications, such as in control systems, instrumentation, and signal processing. V/F converters are used to convert an input voltage signal into an output frequency signal, while F/V converters are used to convert an input frequency signal into an output voltage signal. V/F and F/V converters are often used in conjunction with other electronic components, such as amplifiers or filters, to provide a precise, stable voltage or frequency output signal that can be used by a system or device.
