What Does VFO Stand For?

VFO stands for Variable Frequency Oscillator

A Variable Frequency Oscillator (VFO) is an electronic circuit that generates a periodic signal with a frequency that can be adjusted over a range. It is commonly used in radio communications and signal processing applications to provide a tunable frequency source, enabling the mixing of signals for modulation and demodulation purposes. VFOs play a critical role in synthesizers, transmitters, and receivers, contributing to precise frequency control and signal generation.
