1Operational amplifier — A Signetics μa741 operational amplifier, one of the most successful op amps. An operational amplifier ( op amp ) is a DC coupled high gain electronic voltage amplifier with a differential input and, usually, a single ended output.[1] An op amp… …
2Active Electronically Scanned Array — An Electronically Scanned Array (AESA), also known as active phased array radar is a type of radar whose transmitter and receiver functions are composed of numerous small transmit/receive (T/R) modules. AESA radars feature short to instantaneous… …
3Operational transconductance amplifier — Schematic symbol for the OTA. Like the standard operational amplifier, it has both inverting (−) and noninverting (+) inputs; power supply lines (V+ and V−); and a single output. Unlike the traditional op amp, it has two additional biasing inputs …
4Headphone amplifier — A headphone amplifier is a kind of audio amplifier designed particularly to drive headphones instead of loudspeakers. Most commonly they are found embedded in electronic devices such as integrated amplifiers, portable music players and… …
5List of vacuum tubes — This is a list of vacuum tubes or thermionic valves. Before the advent of semiconductor devices, hundreds of tube types were used in consumer and industrial electronics; today only a few types are still used in specialized applications. Contents… …
6radar — /ray dahr/, n. 1. Electronics. a device for determining the presence and location of an object by measuring the time for the echo of a radio wave to return from it and the direction from which it returns. 2. a means or sense of awareness or… …
7ISAR — Ein Synthetic Aperture Radar (Abkürzung: SAR; deutsch etwa: „Radar mit synthetischer Apertur“) gehört ebenso wie ein Real Aperture Radar (Abkürzung: RAR; deutsch: „Radar mit echter Apertur“) zur Klasse der abbildenden Radare. Es wird aus… …
8Seitensichtradar — Ein Synthetic Aperture Radar (Abkürzung: SAR; deutsch etwa: „Radar mit synthetischer Apertur“) gehört ebenso wie ein Real Aperture Radar (Abkürzung: RAR; deutsch: „Radar mit echter Apertur“) zur Klasse der abbildenden Radare. Es wird aus… …
