What is a Low frequency oscillator?

A Low-Frequency Oscillator (LFO) is a device that generates periodic signals at low frequencies, typically in the range of a few Hz to several kHz. It is used in various audio and electronic applications for waveform modulation, filtering, and signal modulation. LFOs are commonly found in sound synthesis equipment, synthesizers, and motor control systems. They are often used to create effects such as tremolo or phasing in audio signals. By adjusting the frequency of the generated signal, an LFO can produce different effects in a variety of electronic devices.

Application of Low frequency oscillator

✅Changing Sound Characteristics in Audio Equipment
In synthesizers, the LFO is used to modulate and filter sound, adding effects like tremolo or vibrato.
✅Motor Control
Low-frequency oscillators are sometimes used to modulate the speed or torque of motors.
✅Creating Audio Effects
LFOs are used in synthesizers or effects processors to modulate waveforms and emphasize effects such as reverb or delay.
✅Signal Processing
In communication or audio equipment, LFOs are used to adjust the phase or frequency of a signal to add modulation effects.
