Talk:Electronics/Definitions

I like the look of the "official" definition syntax, too. Does anyone else like it better? - Omegatron 14:15, 26 May 2004 (UTC)


 * AC : Alternating current. Consists of a periodic oscillation between two different voltages.  Usually said to look like a sine wave, but is not always.


 * AM : Amplitude modulation. In radio communications, a signal controls the amplitude of a carrier wave that is at a much higher, constant frequency.  The carrier wave is filtered out and a loudspeaker plays based on the amplitude of the signal.


 * Ampere, Amp (A) : The SI unit for current I. Equals a coulomb (1 C) of charged particles moving past a point in one second (1 s).
 * $$A = \frac{C}{s}$$


 * Amplify : To increase the strength of the signal.


 * Anode : An electron collector. Means up the path from a negative to a positive voltage.  An anode has a more positive voltage relative to some other place.


 * Attenuate : Decrease the strength of a signal.


 * Band-Pass Filter : An analog filter that absorbs low and high frequencies (f) but allows a band of frequencies in the middle to pass through.


 * BJT : Bi-polar junction transistor. A transistor in which the resistance of the channel is controlled by a current at the gate.  Can be thought of as a current-controlled resistor.  FET is the other major type of transistor.


 * Capacitor : An electronics component that stores energy in the form of electric charge (static electricity). It resists a sudden change in voltage.

improvement is necessary in this page....definations which are given above are not very clear....
