2. Fundamental frequencyThe fundamental frequency, often referred to simply as the fundamental and abbreviated as f0 (or FF), is defined as the lowest frequency of a periodic waveform. In terms of a superposition of sinusoids, the fundamental frequency is the lowest frequency sinusoidal in the sum. All sinusoidal and many non-sinusoidal waveforms are periodic, which is to say they repeat exactly over time. A single period is thus the smallest repeating unit of a signal, and one period describes the signal completely.
