## FUNDAMENTALFREQUENCY

### Fundamental frequency

The**fundamental frequency**, often referred to simply as the

**fundamental**, 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. In some contexts, the fundamental is usually abbreviated as

**, indicating the lowest frequency counting from zero. In other contexts, it is more common to abbreviate it as**

*f*_{0}**, the first harmonic.**
