Frequency and Fundamental Frequency

This section helps you to understand the frequency and the fundamental frequency.

Frequency measures the number of times that a periodic phenomenon occurs per unit of time. A wave frequency measures the number of cycles per second of the repeating wave. Hertz is the unit for frequency. Frequency band is a range of frequency between two boundary frequencies.

The fundamental frequency, also referred to as the fundamental, is the lowest frequency of a harmonic series. If the frequencies of a harmonic series are noted k.f0, with k = 1, 2, 3 ..., then f0 is the fundamental.
