A Geiger tube is still the sensing device, but the processing electronics will have a higher degree of sophistication and reliability than that used in a hand held survey meter.

As a rectifying diode, and forerunner to the triode valve and many related structures, it can also be considered to be the device that gave birth to modern electronics.

In the ensuing years, valves quickly superseded " cat ’ s whiskers " and were the main device used to create the huge electronics industry that we take for granted today.

MEMS became practical once they could be fabricated using modified semiconductor device fabrication technologies, normally used to make electronics.

Digital cameras use an electronic image sensor based on light-sensitive electronics such as charge-coupled device ( CCD ) or complementary metal-oxide-semiconductor ( CMOS ) technology.

The triode vacuum tube was the first electronic amplification device, which propelled the electronics age forward, by enabling amplified radio technology and long-distance telephony.

In electronics, a vacuum tube, electron tube ( in North America ), thermionic valve, tube, or valve is a device controlling electric current through a vacuum in a sealed container.

Some designs might contain a radioisotope thermoelectric generator using Pu-238 to provide a long lasting source of electrical power for the electronics in the device.

* Attenuator ( electronics ), an electronic device that reduces the amplitude of an electronic signal

In electronics, a comparator is a device that compares two voltages or currents and switches its output to indicate which is larger.

The SOIC ( Small Outline IC ), a surface-mount package which is currently very popular, particularly in consumer electronics and personal computers, is essentially a shrunk version of the standard IC PDIP, the fundamental difference which makes it an SMT device being a second bend in the leads to flatten them parallel to the bottom plane of the plastic housing.

An electronics device:

* Terminal ( electronics ), a device for joining electrical circuits together

In electronics and telecommunications a transmitter or radio transmitter is an electronic device which, with the aid of an antenna, produces radio waves.

On the other hand, activation-critical electronics within the weapon, such as capacitors, are selected so that they will fail before the safety device in the event of damage, ensuring that the weapon fails safe.

* An analog telephone adapter is a device that connects to the network and implements the electronics and firmware to operate a conventional analog telephone attached through a modular phone jack.

Digital cameras use electronics, usually a charge coupled device ( CCD ) to store digital images in computer memory inside the camera.

In electronics, the linear operating region of a device, for example a transistor, is where a dependent variable ( such as the transistor collector current ) is directly proportional to an independent variable ( such as the base current ).

Reflecting the largest percentage of high-end sets such as consoles and combinations since 1953, dollar value of home entertainment electronics in 1960 was about $1.9 billion, compared to $1.7 billion in 1959.

The electronics of the memory and arithmetic units could store and operate on 60 such numbers at a time ( 3000 bits ).

These qualities make UV curing adhesives essential to the manufacturing of items in many industrial markets such as electronics, telecommunications, medical, aerospace, glass, and optical.

Applications such as ion implantation may be used to identify the distribution of dopants inside a semi-conducting material, which is increasingly critical in the correct design of modern nanometre scale electronics.

RoHS seeks to limit the dangerous substances in circulation in electronics products, in particular toxins and heavy metals, which are subsequently released into the environment when such devices are recycled.

In Canada, the Department of Industry is responsible for allocating frequencies and call signs, managing the broadcast spectrum, and regulating other technical issues such as interference with electronics equipment.

Since diamond has the highest thermal conductivity of any bulk material, layering diamond onto high heat producing electronics ( such as optics and transistors ) allows the diamond to be used as a heat sink.

Although these early hand-held calculators were very expensive, these advances in electronics, together with developments in display technology ( such as the vacuum fluorescent display, LED, and LCD ), lead within a few years to the cheap pocket calculator available to all.

In electronics, counters can be implemented quite easily using register-type circuits such as the flip-flop, and a wide variety of classifications exist:

The term " embedded database " can be confusing because only a small subset of embedded database products is used in real-time embedded systems such as telecommunications switches and consumer electronics devices.

Signal Processing is a very mathematically oriented and intensive area forming the core of digital signal processing and it is rapidly expanding with new applications in every field of electrical engineering such as communications, control, radar, TV / Audio / Video engineering, power electronics and bio-medical engineering as many already existing analog systems are replaced with their digital counterparts.

* electronics which deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes and integrated circuits, and associated passive interconnection technologies.

The components in an electric circuit can take many forms, which can include elements such as resistors, capacitors, switches, transformers and electronics.

Interconnection technologies such as circuit boards, electronics packaging technology, and other varied forms of communication infrastructure complete circuit functionality and transform the mixed components into a working system.

Historically, electronics labs have consisted of electronics devices and equipment located in a physical space, although in more recent years the trend has been towards electronics lab simulation software, such as CircuitLogix, Multisim, and PSpice.

Today's electronics engineers have the ability to design circuits using premanufactured building blocks such as power supplies, semiconductors ( such as transistors ), and integrated circuits.

Most modern day electronics now use printed circuit boards made of materials such as FR4, or the cheaper ( and less hard-wearing ) Synthetic Resin Bonded Paper ( SRBP, also known as Paxoline / Paxolin ( trade marks ) and FR2 )-characterised by its light yellow-to-brown colour.

Simple additive mixers use Kirchhoff's circuit laws to add the currents of two or more signals together, and this terminology (" mixer ") is only used in the realm of audio electronics where audio mixers are used to add together audio signals such as voice signals, music signals, and sound effects.

Very different mathematical treatments apply to the design of filters termed infinite impulse response ( IIR ) filters, characteristic of mechanical and analog electronics systems, and finite impulse response ( FIR ) filters, which can be implemented by discrete time systems such as computers ( then termed digital signal processing ).

Historically the first decade of semiconductor electronics were entirely based on germanium, although its production for such use today is a small fraction ( 2 %) of that of ultra-high purity silicon, which has largely replaced it.

The period saw a shift from an agriculture-based economy to one based on manufacturing and industry in areas such as computers and consumer electronics.

The newer Ibanez models began incorporating more modern elements into their design such as radical body shapes, slimmer necks, 2-octave fingerboards, slim pointed headstocks, higher-output electronics, humbucker / single-coil / humbucker ( H / S / H ) pickup configurations, locking tremolo bridges and different finishes.
