Frequency spectrum — Familiar concepts associated with a frequency are colors, musical notes, radio/TV channels, and even the regular rotation of the earth. A source of light can have many colors mixed together and in different amounts (intensities). A rainbow, or… … Wikipedia

Frequency counter — A frequency counter is an electronic instrument, or component of one, that is used for measuring frequency. Since frequency is defined as the number of events of a particular sort occurring in a set period of time, measuring it is usually… … Wikipedia
Matrix (geology) — Potassium feldspar phenocrysts within a fine grained matrix in a granite porphyry. The matrix or groundmass of rock is the finer grained mass of material in which larger grains, crystals or clasts are embedded. The matrix of an igneous rock… … Wikipedia
Short-time Fourier transform — The short time Fourier transform (STFT), or alternatively short term Fourier transform, is a Fourier related transform used to determine the sinusoidal frequency and phase content of local sections of a signal as it changes over time. STFT… … Wikipedia
Discrete-time Fourier transform — In mathematics, the discrete time Fourier transform (DTFT) is one of the specific forms of Fourier analysis. As such, it transforms one function into another, which is called the frequency domain representation, or simply the DTFT , of the… … Wikipedia
Negative frequency — The concept of negative and positive frequency can be as simple as a wheel rotating one way or the other way.[citation needed] A signed value of frequency indicates both the rate and direction of rotation.[citation needed] The rate is expressed… … Wikipedia
