RF power amplifier — An RF power amplifier is a type of electronic amplifier used to convert a low power radio frequency signal into a larger signal of significant power, typically for driving the antenna of a transmitter. It is usually optimized to have high… … Wikipedia
Intermediate power amplifier — An Intermediate power amplifier (IPA) is one stage of the amplification process in a radio transmitter which usually occurs prior to the final high power amplification. The IPA provides lower power RF energy necessary to drive the final. In very… … Wikipedia
High fidelity — or hi fi reproduction is a term used by home stereo listeners and home audio enthusiasts (audiophiles) to refer to high quality reproduction of sound or images that are very faithful to the original master recording. High fidelity equipment has… … Wikipedia
High-end audio cables — are claimed to improve the sound quality of high fidelity audio systems but whether they actually do is hotly disputed. Since the audio signal passes through cables on its way from the source to the amplifier, or from the amplifier to the… … Wikipedia
Amplifier — For other uses, see Amplifier (disambiguation). Generally, an amplifier or simply amp, is a device for increasing the power of a signal. In popular use, the term usually describes an electronic amplifier, in which the input signal is usually a… … Wikipedia
Frequency modulation — See also: Amplitude modulation In telecommunications, frequency modulation (FM) conveys information over a carrier wave by varying its frequency (contrast this with amplitude modulation, in which the amplitude of the carrier is varied while its… … Wikipedia
High voltage — The term high voltage characterizes electrical circuits, in which the voltage used is the cause of particular safety concerns and insulation requirements. High voltage is used in electrical power distribution, in cathode ray tubes, to generate X… … Wikipedia
Frequency divider — A frequency divider, also called a clock divider or scaler or prescaler, is a circuit that takes an input signal of a frequency, fin, and generates an output signal of a frequency: where n is an integer. Phase locked loop frequency synthesizers… … Wikipedia
