Electronic equipment that increases strength of signals passing through it.
A device which draws power from a source other than the input signal and which produces as an output an enlarged reproduction of the essential features of its input.
Electronic device that magnifies the strength of a signal, such as a radio signal. The ratio of output signal strength to input signal strength is called the gain of the amplifier. As well as achieving high gain, an amplifier should be free from distortion and able to operate over a range of frequencies. Practical amplifiers are usually complex circuits, although simple amplifiers can be built from single transistors or valves. + prikaži više
