Low-Frequency Oscillation

Low-Frequency Oscillation (LFO) refers to slow, rhythmic fluctuations in a system's activity, such as in electronics or biological signals. In technology, it often describes slow changes in audio signals or control voltages that modulate other signals or parameters, creating effects like vibrato or tremolo. In neuroscience, LFOs are brainwave patterns occurring at low frequencies that influence mental states and behaviors. These oscillations help systems synchronize or coordinate activity across different components, and their slow pace allows for processes like adaptation, regulation, or the generation of rhythmic patterns.
