high-gain power amplifier
31Low-noise amplifier — The low noise amplifier (LNA) is a special type of electronic amplifier or amplifier used in communication systems to amplify very weak signals captured by an antenna. It is often located very close to the antenna, so that losses in the feedline… …
32Tower Mounted Amplifier — Crowded mast with TMAs (white rectangular boxes) mounted behind all the panel (rectangular) antennas A Tower Mounted Amplifier or Mast Head Amplifier is a Low noise amplifier (LNA) mounted as close as practical to the antenna in mobile masts or… …
33Differential gain — is a kind of linearity distortion which affects the color saturation in TV broadcasting. Contents 1 Composite color video signal 2 Non linearity in the broadcast system 3 Differential gain …
34Class T amplifier — Two Tripath chipset Class T stereo amplifier modules. TA2024 6+6W to the left, TA2020 20+20W to the right …
35Half power point — The half power point of an electronic amplifier stage is that frequency at which the output power has dropped to half of its mid band level. This occurs when the output voltage has dropped by 3 dB and the power has dropped by half. A bandpass… …
36Loop gain — In negative feedback amplifiers, loop gain refers to the product of the gain in the feedback loop and the feedback factor in that loop. In Figure 1, the loop gain is the product β A OL.In telecommunication, the term loop gain has the following… …
37Guitar effects — are electronic devices that modify the tone, pitch, or sound of an electric guitar, or condition or reroute the signal in some fashion. Effects can be housed in small effects pedals ( stomp boxes ), guitar amplifiers, guitar amplifier simulation… …
38Logic gate — A logic gate is an idealized or physical device implementing a Boolean function, that is, it performs a logical operation on one or more logic inputs and produces a single logic output. Depending on the context, the term may refer to an ideal… …
39Direct-conversion receiver — A direct conversion receiver (DCR), also known as homodyne, synchrodyne, or zero IF receiver, is a radio receiver design that demodulates the incoming radio signal using synchronous detection driven by a local oscillator whose frequency is… …
40Driven right leg circuit — A Driven Right Leg Circuit or “DRL” circuit is an electric circuit that is often added to biological signal amplifiers to reduce Common mode interference. Biological signal amplifiers such as EKG (Electrocardiogram) EEG (Electroencephalogram) or… …
