Electronics Electronics An electrical circuit consists of various components or devices or elements, which may be active or passive. Active devices are sources of energy, converting between forms of energy: chemical, hydraulic, thermal energy, mechanical , nuclear, solar, etc, into electrical energy, driving electrical current around the circuit and hence delivering continuous energy to it. ...more on Wikipedia about "Active device"

To reduce the output volume of an audio amplifier you may use a device called an Attenuator (please see:http://en.wikipedia.org/wiki/Attenuator for a more broad based discussion). These devices use electrical resistance to reduce the amplitude of the signal that reaches the speaker, effectively making the amp quieter. Various methods are used, from the original Altair that was purely resistive, through various methods that add some electrical inductance or reactivity to the electrical load (including fans, light bulbs and coils). Many people feel that reactive attenuators do a better job of preserving the amp's tone. These devices can also be designed to put out a line level signal tapped off of the speaker's leads that can be recorded directly or reamplified through a larger or smaller amp for more or less volume. ...more on Wikipedia about "Amplifier attenuators"
Analogue Electronics refers to electronics systems with analogue signals with any continuously variable signal. It differs from digital electronics in that small fluctuations in the signal are meaningful in that they are continuously variable rather than digitally quantised. Analogue is usually thought of in an electrical context, however mechanical, pneumatic, hydraulic, and other systems may also use analogue signals. Analogue Electronics is frequently confused with other sub-divisions of the general field of Electronics which include Power electronics and Digital electronics. ...more on Wikipedia about "Analogue electronics"
Angle notation or phasor notation is a notation used in electronics using the ∠ sign. It is an abbreviation that arose due to the frequent occurrence of the expression ej φ and is used to describe phasors. Note that the phase angle φ is almost always written in degrees. ...more on Wikipedia about "Angle notation"
An antenna analyzer (or noise bridge, or RX bridge) is a bridge where two legs are frequency-dependent complex-valued impedances. When the two impedances are the same the bridge will be balenced. Uisng this circuit it is possible to either measure the impedance of the antenna connected between ANT and GND, or it is possible to adjust an antenna until it has the same impedance as the network on the left hand side. The bridge can be driven either with white noise or a simple carrier (connected to drive). In the case of white noise the amplitude of the exciting signal can be very low and a radio receiver used as the detector. In the case where a simple carrier is used then depending on the level either a diode detector or a receiver can be used. In both cases a null will indicate when the bridge is balenced. ...more on Wikipedia about "Antenna analyzer"
An antenna tuner, transmatch, antenna tuning unit, or ATU matches a transceiver with a fixed impedance (typically 50 ohms for modern transceivers) to a load (feed line and antenna) impedance which is unknown, complex or otherwise does not match. This mismatch is usually caused when using a non- resonant antenna, one that is not the correct electrical length as compared to the wavelength of the signal. An ATU allows the use of one antenna for a broad range of frequencies. A tuned antenna is never as good as a naturally resonant antenna due to additional induced losses on the feed line due to the multiple reflections, and losses in the ATU itself. ...more on Wikipedia about "Antenna tuner"

Audio crossovers are a class of electronic filters designed specifically for use in audio applications, especially hi-fi. A commonly used dynamic loudspeaker driver is incapable of covering the entire audio spectrum all by itself. Thus, crossovers serve the purpose of splitting the audio signal into separate frequency bands which can be handled by individual loudspeaker drivers optimized for those bands. A combination of multiple drivers each catering to a different frequency band constitutes most hi-fi speaker systems. An audio crossover may also be constructed mechanically and is commonly found in full-range speakers. ...more on Wikipedia about "Audio crossover"
Audio electronics is the branch of electronics which deals specifically with audio and sound related technologies. Audio electronics derives most of its circuits from mainstream electronics but (sometimes) slightly modified for the specific needs of sound reproduction. The following is a partial list of audio-related circuits/techniques/devices: ...more on Wikipedia about "Audio electronics"
The onboard electronics used for piloting an aircraft are called avionics (AVI-ation electr-ONICS). Avionics include communications and navigation systems, autopilots, and electronic flight management systems (FMS). Onboard electronics that are unrelated to piloting tasks, such as video systems for passengers, are sometimes considered avionics as well. Many of these devices include embedded computers. ...more on Wikipedia about "Avionics"
In Computing, a Backplane System is a generic term for a printed circuit board whose purpose is to interconnect other circuit boards. A backplane will typically contain various sockets into which the daughter circuit boards will be plugged in. ...more on Wikipedia about "Backplane system"
A basing diagram shows or describes the “pins” of an electronic component. This part usually has more than two pins, so a basing diagram is needed to show which pin does what. Many basing diagrams also show dimensions. ...more on Wikipedia about "Basing diagram"
Beamforming is a signal processing technique used with arrays of transmitters or receivers that controls the directionality of, or sensitivity to, a radiation pattern. When receiving a signal, beamforming can increase the gain in the direction of wanted signals and decrease the gain in the direction of interference and noise. When transmitting a signal, beamforming can increase the gain in the direction the signal is to be sent. This is done by creating beams and nulls in the radiation pattern. Beamforming can also be thought of as spatial filtering. ...more on Wikipedia about "Beamforming"

(Braid-breaker) The braid breaker is a term for one of the best filters for preventing TVI. It is the case that in many cases of TeleVision Interferance caused by a high field strength of a nearby HF transmitter that the aerial downlead plugged into the back of the TV acts as a longwire antenna or as a simple vertical element. The RF current flowing through the tuner of the TV tends to generate harmonics which then spoil the viewing. ...more on Wikipedia about "Braid-breaker"

Circuit design is the process of working out the physical form that an electronic circuit will take, ** physical form includes the choice of method of construction as well as all the parts and materials to be used. It also covers the choice of what electronic components will be used and the physical layout they are to take. The process of circuit design can cover systems ranging from national power grids all the way down to the individual transistors within an integrated circuit. For simple circuits the design process can often be done by one person simply designing the circuit as they go along, but for more complex designs, teams of designers following a systematic approach with intelligently guided computer simulation are becoming an increasingly dominant aspect. ...more on Wikipedia about "Circuit design"

A clamp or clamp circuit is an electrical circuit used to prevent another circuit from exceeding a certain predetermined voltage level. It operates by sensing the output voltage of the monitored circuit and then if the output voltage threatens to exceed the preset limit, applies an electric load which draws greater and greater current from the output in a regulated manner in order to prevent the output voltage from exceeding the predetermined voltage level. The clamp circuit works only if it has a lower output impedance than the monitored circuit thereby overpowering that circuit. ...more on Wikipedia about "Clamp (circuit)"
