discrete digital input
1Digital electronics — Main articles: Electronics and Electronic circuit Digital electronics represent signals by discrete bands of analog levels, rather than by a continuous range. All levels within a band represent the same signal state. Relatively small changes to… …
2Digital signal processing — (DSP) is concerned with the representation of discrete time signals by a sequence of numbers or symbols and the processing of these signals. Digital signal processing and analog signal processing are subfields of signal processing. DSP includes… …
3Digital control — is a branch of control theory that uses digital computers to act as system controllers. Depending on the requirements, a digital control system can take the form of a microcontroller to an ASIC to a standard desktop computer. Since a digital… …
4Discrete 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,… …
5Digital processing — is the process of altering digital data in any form.The most common situations where digital processing is involved are computer graphics and digital audio processing. The two are related regarding both the problems encountered and the solutions… …
6Digital Equipment Corporation — Industry Computer manufacturing Fate Assets were sold to various companies. What remained was sold to Compaq. Successor …
7Discrete Fourier transform — Fourier transforms Continuous Fourier transform Fourier series Discrete Fourier transform Discrete time Fourier transform Related transforms In mathematics, the discrete Fourier transform (DFT) is a specific kind of discrete transform, used in… …
8Digital filter — A general finite impulse response filter with n stages, each with an independent delay, di, and amplification gain, ai. In electronics, computer science and mathematics, a digital filter is a system that performs mathematical operations on a… …
9digital computer — a computer that processes information in digital form. Cf. analog computer. [1940 45] * * * Computer capable of solving problems by processing information expressed in discrete form. By manipulating combinations of binary digits (see binary code) …
10Discrete 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… …
