Schematic of an AGC used in the analog telephone network; the feedback from output level to gain is effected via a Vactrol resistive opto-isolator.. Automatic gain control (AGC) is a closed-loop feedback regulating circuit in an amplifier or chain of amplifiers, the purpose of which is to maintain a suitable signal amplitude at its output, despite variation of the signal amplitude at the input.

A mobile simulator is a software application for a personal computer which creates a virtual machine version of a mobile device, [1] such as a mobile phone, iPhone, other smartphone, or calculator, on the computer. This may sometimes also be termed an emulator.
A cellular repeater (also known as cell phone signal booster or cell phone signal amplifier) is a type of bi-directional amplifier used to improve cell phone reception. [citation needed] A cellular repeater system commonly consists of a donor antenna that receives and transmits signal from nearby cell towers, coaxial cables, a signal amplifier, and an indoor rebroadcast antenna.
A display of bars on a mobile phone screen. A mobile phone signal (also known as reception and service) is the signal strength (measured in dBm) received by a mobile phone from a cellular network (on the downlink). Depending on various factors, such as proximity to a tower, any obstructions such as buildings or trees, etc. this signal strength ...
A front-of-house sound engineer with a Digidesign D-Show Profile live digital mixer and a computer monitor. Setting up sound reinforcement for live music clubs and dance events often poses unique challenges, because there is such a large variety of venues that are used as clubs, ranging from former warehouses or music theaters to small ...
The first practical version of such devices was the Audion triode, invented in 1906 by Lee De Forest, [8] [9] [10] which led to the first amplifiers around 1912. [11] Since the only previous device which was widely used to strengthen a signal was the relay used in telegraph systems, the amplifying vacuum tube was first called an electron relay.
Pizza Tycoon (also known as Pizza Connection in Europe) is a business simulation video game. The game was designed by the German company Cybernetic Corporation [ 1 ] and Software 2000 in 1994, [ 2 ] and was published by Assemble Entertainment after its re-release in 2017.
