Discrete frequency — is defined as the frequency with which the samples of a discrete sinusoid occur. Just as in its continuous time counterpart (see frequency), the discrete time signal has a time axis, conventionally denoted by n . The time variable n , however,… … Wikipedia
Sampling (statistics) — Sampling is that part of statistical practice concerned with the selection of individual observations intended to yield some knowledge about a population of concern, especially for the purposes of statistical inference. Each observation measures… … Wikipedia
Sampling — may refer to: Sampling (signal processing), converting a continuous signal into a discrete signal Sampling (graphics), converting continuous colors into discrete color components Sampling (music), re using portions of sound recordings in a piece… … 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
Sampling (signal processing) — Signal sampling representation. The continuous signal is represented with a green color whereas the discrete samples are in blue. In signal processing, sampling is the reduction of a continuous signal to a discrete signal. A common example is the … Wikipedia
Discrete time — This article is about discrete time in signal processing. For discrete time in quantum physics, see quantum time. Discrete time is the discontinuity of a function s time domain that results from sampling a variable at a finite interval. For… … Wikipedia
Sampling rate — Analog signal and resulting sampled signal. The sampling rate, sample rate, or sampling frequency defines the number of samples per second (or per other unit) taken from a continuous signal to make a discrete signal. For time domain signals, it… … Wikipedia
Discrete cosine transform — A discrete cosine transform (DCT) expresses a sequence of finitely many data points in terms of a sum of cosine functions oscillating at different frequencies. DCTs are important to numerous applications in science and engineering, from lossy… … Wikipedia
Discrete system — A discrete system is a system with a countable number of states. Discrete systems may be contrasted with continuous systems, which may also be called analog systems. A final discrete system is often modeled with a directed graph and is analyzed… … Wikipedia
