Fundamental Frequency 1
Fundamental Frequency 1 : 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 (e.g. Fourier series), the fundamental frequency is the lowest frequency sinusoidal in the sum. In some contexts, the fundamental is usually abbreviated as?f0?(or?FF), indicating the lowest frequency counting from zero. In other contexts, it is more common to abbreviate it as?f1, the first harmonic. (The second harmonic is then f2?= 2?
