An op-amp, defined as a general-purpose, DC-coupled, high gain, inverting feedback amplifier, is first found in " Summing Amplifier " filed by Karl D. Swartzel Jr. of Bell Labs in 1941.

An operational amplifier (" op-amp ") is a DC-coupled high-gain electronic voltage amplifier with a differential input and, usually, a single-ended output.

RS-232 has been standard for so long that the circuits needed to control a serial port became very cheap and often exist on a single chip, sometimes also with circuitry for a parallel port.

Soon the problem became that the chips could hold more circuitry than the designers knew how to use.

Originally the gas flow computer was a mechanical ( 1920s technology ) or later a pneumatic or hydraulic computing module ( 1940s technology used to the early 1990s but still available from a number of suppliers ), subsequently superseded in most applications by an electronic module, as the primary elements switched from transmitting the measured variables from pneumatic or hydraulic pressure signals to electric current as explosion-proof ( 1960s technology to present )) and then intrinsically-safe ( 1970s to present ) transmitters ( with low power transistor circuitry ) became available, that simply provided a dedicated gas flow computer function.

The circuitry usually includes a delay that leaves the circuit activated for a short time after the sound stops.

The video circuitry started drawing the sprites after the timer had expired, allowing them to be displayed with no manipulation of memory.

One proposed method would be to " paint " the probe and its circuitry onto an enormous sheet of plastic which degrades when exposed to ultraviolet light, and then wait for the sheet to evaporate away under the assault of solar UV after it has been deployed in space.

The device typically starts to conduct the current imposed by the external circuitry after some nanoseconds or microseconds but the complete switch on of the whole junction takes a much longer time, so too swift a current rise may cause local hot spots that can permanently damage the TRIAC.

Additional auxiliary circuitry may be needed in DC ( and some AC ) applications to suppress follow-on current, to prevent it from destroying the GDT after the initiating spike has dissipated.

Tantalum films provide the second most capacitance per volume of any substance after Aerogel, and allow miniaturization of electronic components and circuitry.

With mathematical notation, Rosenblatt also described circuitry not in the basic perceptron, such as the exclusive-or circuit, a circuit whose mathematical computation could not be processed until after the backpropagation algorithm was created by Werbos ( 1975 ).

From then on the wafer is repeatedly processed in this fashion, putting on layer after layer of circuitry on the surface.

Although the wafer is aligned after it is placed on the wafer stage, this alignment is not sufficient to ensure that the layer of circuitry to be printed onto the wafer exactly overlays previous layers already there.

In order to test their new circuitry, they first built a small 18-bit machine known as TX-0 which first ran in 1956.

These properties however can become important when circuitry is subjected to transients, such as when first energised.

When power is first applied to the motherboard, the BIOS firmware tests and configures memory, circuitry, and peripherals.

Reduced instruction-set computers, RISC, were first widely implemented during a period of rapidly growing memory subsystems and sacrifice code density in order to simplify implementation circuitry and thereby try to increase performance via higher clock frequencies and more registers.

The world's first solid state circuitry colour televisions were manufactured by Ferguson at their now closed plant in Enfield.

In 1986, they introduced the WD33C93 single-chip SCSI interface, which was used in the first 16-bit bus mastering SCSI host adapter, the WD7000 " FASST "; in 1987 they introduced the WD37C65, a single-chip implementation of the PC / AT's floppy disk controller circuitry, and the grandfather of modern super I / O chips ; in 1988 they introduced the WD42C22 " Vanilla ", the first single-chip ATA hard disk controller.

In November, the Stone Roses performed a gig at London's Alexandra Palace which was a nightmare, with 8000 fans and only 2 bar staff, and were invited onto BBC2's high-brow Late Show ( remembered by many because the electricity was cut by off by noise limiting circuitry within seconds of them starting the first chorus of " Made of Stone " and lead singer, Ian Brown, shouted " Amateurs, amateurs " as the presenter tried to link into the next item ).

Ashley engineered the first version of the piece using live electronics and reactive computer circuitry.

He was permitted to become the Naval Academy's first graduate to be commissioned directly into the Supply Corps, which did not necessitate being able to tell the difference between red ( port ) and green ( starboard ) lights or to discern the color differences in electrical circuitry.

The first practical electronic hearing aid with adjustable analog audio circuitry was based on US Patent 2, 017, 358, " Hearing Aid Apparatus and Amplifier " by Samual Gordon Taylor, filed in 1932.

The first hearing aid with analog audio circuitry and automatic digital electronic control circuitry was based on US Patent 4, 025, 721, " Method of and means for adaptively filtering near-stationary noise from speech " by D Graupe, GD Causey, filed in 1975.

This confirms that muscle strength is first influenced by the inner neural circuitry, rather than by external physiological changes in the muscle size.

Using a moving stylus, these layouts were organized in layers, first placing the smaller common and custom circuits, created in a library, then manually traced their interconnecting circuitry on further layers, the completed layout then stored in computer files.

Its first circuitry layout was designed on an earlier home-made computer ( built using ASMP of three KR580 chips, the Soviet clones of Intel 8080 ), by Dmitry Mikhilov as well.

The first generation electronic systems were quirky devices with cantankerous punched card readers for loading keys and failure-prone, tricky-to-maintain vacuum tube circuitry.

In the first film, Professor X mentions to Wolverine that Magneto helped him build it, and therefore knows how to construct helmets with circuitry to block its detection abilities.

The first step, placement, involves deciding where to place all electronic components, circuitry, and logic elements in a generally limited amount of space.

The first " Tiny Terror " channel features the same circuitry as the Tiny Terror amp.

The first Model 202s were produced simply by installing the anti-sidetone circuitry into existing Model 102s.

Designed by Henry Dreyfuss, it was the first widely-used American subscriber set to include the ringer and anti-sidetone circuitry in the same unit as the rest of the subscriber set ; prior Western Electric models required the use of an external “ subset ” ( ringer box ).

Later, the HP300 design team over came the first generation HP300 slower TTL circuitry with a SOS design ( project name: Sizzler ).

* Nikola Tesla was famous for developing the AC motor, the bifilar coil, various devices that used rotating magnetic fields, the alternating current polyphase power distribution systems, the fundamental devices of systems of wireless communication ( legal priority for the invention of radio ), radio frequency oscillators, devices for voltage magnification by standing waves, robotics, logic gates for secure radio frequency communications, devices for x-rays, apparatus for ozone generation, devices for ionized gases, devices for high field emission, devices for charged particle beams, methods for providing extremely low level of resistance to the passage of electrical current, means for increasing the intensity of electrical oscillations, voltage multiplication circuitry, devices for high voltage discharges, devices for lightning protection and VTOL aircraft.

The Polymoog was an attempt to create a truly polyphonic analog synthesizer, with sound generation circuitry for every key on the keyboard.

* Ease of replacement — Power supplies are more prone to failure than other circuitry due to their exposure to power spikes and their internal generation of waste heat.

The earliest bass pedals from the 1970s consisted of a pedalboard and analog synthesizer tone generation circuitry packaged together as a unit.

Although vacuum tubes are far more resistant to EMP than solid state devices, other components in vacuum tube circuitry can be damaged by EMP.

In solid state electronics all of these techniques can be used, and phase inversion can also be produced by the use of NPN / PNP complementary circuitry, which has no corresponding technique in vacuum tube designs.

Although the 709 was a superior machine to its predecessor, the 704, it was being built and sold at the time that transistor circuitry was supplanting vacuum tube circuits.

This technology was originally pioneered in the 1930s by researchers at General Electric using vacuum tube circuitry.

The later adoption of the tetrode vacuum tube eliminated the Miller capacitance and the need for this touchy circuitry.

The ECME built by Sargrove produced all of the radio circuitry by the sprayed-circuit process, and assembled all of the radio parts except for inserting the vacuum tubes into their sockets and attaching the speaker, thus greatly reducing the amount of human labor required and thereby lowering the cost of the radios.

The amplifiers featured solid-state circuitry instead of vacuum tube-based designs so common in the 1960s.
