digital signal processing system
11Quantization (signal processing) — In digital signal processing, quantization is the process of approximating a continuous range of values (or a very large set of possible discrete values) by a relatively small set of discrete symbols or integer values.More specifically, a signal… …
12Digital audio — Digital music redirects here. For a kind of modern music composed by digital means, see electronic music. A sound wave, in gray, represented digitally, in red (after quantization and zero order hold). Digital audio is sound reproduction using… …
13Digital Radio Mondiale — (abbreviated DRM; mondiale being Italian and French for worldwide ) is a set of digital audio broadcasting technologies designed to work over the bands currently used for AM broadcasting, particularly shortwave. DRM can fit more channels than AM …
14Digital radio — has several meanings: 1. Today the most common meaning is digital radio broadcasting technologies, such as the digital audio broadcasting (DAB) system, also known as Eureka 147. In these systems, the analog audio signal is digitized into zeros… …
15Bandwidth (signal processing) — Bandwidth is the difference between the upper and lower cutoff frequencies of, for example, a filter, a communication channel, or a signal spectrum, and is typically measured in hertz. In case of a baseband channel or signal, the bandwidth is… …
16Digital test controller — Digital test controllers are devices (usually computer based) that provide motion control by processing digital signals. Typically a controller has inputs connected to sensors on the device they control, which measure the feedback, its current… …
17Digital 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… …
18Digital Audio Broadcasting — For other digital audio broadcasting systems, see Digital radio.   Countries with regular services …
19Digital 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… …
20Signal (electrical engineering) — In the fields of communications, signal processing, and in electrical engineering more generally, a signal is any time varying or spatial varying quantity. In the physical world, any quantity measurable through time or over space can be taken as… …
