Frequency Addition Source of Optical Radiation — In physics, a FASOR is an acronym for Frequency Addition Source of Optical Radiation. It is a device similar to a laser where the emitted light is produced in a sum frequency generation process from two laser sources that operate at a different… … Wikipedia
Single-sideband modulation — (SSB) is a refinement of amplitude modulation that more efficiently uses electrical power and bandwidth. It is closely related to vestigial sideband modulation (VSB) (see below).Amplitude modulation produces a modulated output signal that has… … Wikipedia
Frequency comb — A frequency comb is the graphic representation of the spectrum of a mode locked laser. An octave spanning comb can be used for mapping radio frequencies into the optical frequency range or it can be used to steer a piezoelectric mirror within a… … Wikipedia
Single-wire transmission line — A single wire transmission line (or single wire method) is a method of supplying electrical power through a single wired electrical conductor. Single wire earth return (SWER) or single wire ground returns today supply single phase electrical… … Wikipedia
Frequency analysis — In cryptanalysis, frequency analysis is the study of the frequency of letters or groups of letters in a ciphertext. The method is used as an aid to breaking classical ciphers.this is wrong is based on the fact that, in any given stretch of… … Wikipedia
Single-phase electric power — In electrical engineering, single phase electric power refers to the distribution of alternating current electric power using a system in which all the voltages of the supply vary in unison. Single phase distribution is used when loads are mostly … Wikipedia
Radio-frequency identification — (RFID) is a technology that uses radio waves to transfer data from an electronic tag, called RFID tag or label, attached to an object, through a reader for the purpose of identifying and tracking the object. Some RFID tags can be read from… … Wikipedia
semiconductor device — ▪ electronics Introduction electronic circuit component made from a material that is neither a good conductor nor a good insulator (hence semiconductor). Such devices have found wide applications because of their compactness, reliability,… … Universalium
Variable-frequency drive — A variable frequency drive (VFD) is a system for controlling the rotational speed of an alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor.cite book | first=Sylvester J. |… … Wikipedia
Multi-frequency network — Introduction Data networks, such as wireless communication networks, have to trade off between services customized for a single terminal and services provided to a large number of terminals. For example, the distribution of multimedia content to… … Wikipedia
Medical device — A medical device is a product which is used for medical purposes in patients, in diagnosis, therapy or surgery[citation needed]. Whereas medicinal products (also called pharmaceuticals) achieve their principal action by pharmacological, metabolic … Wikipedia
