Quadrature amplitude modulation — (QAM) (Pronounced IPA|kwa:m) is a modulation scheme which conveys data by changing ( modulating ) the amplitude of two carrier waves. These two waves, usually sinusoids, are out of phase with each other by 90° and are thus called quadrature… … Wikipedia
Modified Frequency Modulation — This article is about Modified Frequency Modulation. For other uses of MFM, see the MFM (disambiguation). Modified Frequency Modulation, commonly MFM, is a line coding scheme used to encode the actual data bits on most floppy disk formats,… … Wikipedia
Secondary surveillance radar — SSR antenna of Deutsche Flugsicherung at Neubrandenburg, in Mecklenburg/Western Pomerania Secondary surveillance radar (SSR)[1] is a radar system used in air traffic control (ATC), that not only detects an … Wikipedia
Comparison of analog and digital recording — This article compares the two ways in which sound is recorded and stored. Actual sound waves consist of continuous variations in air pressure. Representations of these signals can be recorded using either digital or analog techniques. An analog… … Wikipedia
Halftone — For the music interval, see semitone. Left: Halftone dots. Right: How the human eye would see this sort of arrangement from a sufficient distance. Halftone is the reprographic technique that simulates continuous tone imagery through the use of… … Wikipedia
Teddy Ruxpin — deck built into his back. There was also a companion toy named Grubby which connected to Teddy via a cable; this allowed the two some (minimal) interaction. As well, there were several other non animatronic companion toys and characters such as… … Wikipedia
High-voltage direct current — HVDC or high voltage, direct current electric power transmission systems contrast with the more common alternating current systems as a means for the bulk transmission of electrical power. The modern form of HVDC transmission uses technology… … Wikipedia
Computer fan — A 3D illustration of four 80 mm fans, a type of fan commonly used in personal computers (sometimes as a set, or mixed with other fan sizes). A computer fan is any fan inside, or attached to, a computer case used for cooling purposes, and may… … Wikipedia
Modelocking — Mode locking is a technique in optics by which a laser can be made to produce pulses of light of extremely short duration, on the order of picoseconds (10 12s) or femtoseconds (10 15s).The basis of the technique is to induce a fixed phase… … Wikipedia
Mode-locking — is a technique in optics by which a laser can be made to produce pulses of light of extremely short duration, on the order of picoseconds (10−12 s) or femtoseconds (10−15 s). The basis of the technique is to induce a fixed phase… … Wikipedia
