3. Antenna amplifier - Wikipedia

   en.wikipedia.org/wiki/Antenna_amplifier

   Antenna amplifier for broadcasting service (here: TV broadcasting and FM souns broadcasting. In electronics, an antenna amplifier (also: aerial amplifier or booster) is a device that amplifies an antenna signal, usually into an output with the same impedance as the input impedance. Typically 75 ohm for coaxial cable and 300 ohm for twin-lead ...

4. Optical communications repeater - Wikipedia

   en.wikipedia.org/wiki/Optical_communications...

   An optical communications repeater is used in a fiber-optic communications system to regenerate an optical signal. Such repeaters are used to extend the reach of optical communications links by overcoming loss due to attenuation of the optical fiber. Some repeaters also correct for distortion of the optical signal by converting it to an ...

5. Low-noise amplifier - Wikipedia

   en.wikipedia.org/wiki/Low-noise_amplifier

   Low-noise amplifier. A low-noise amplifier ( LNA) is an electronic component that amplifies a very low-power signal without significantly degrading its signal-to-noise ratio (SNR). Any electronic amplifier will increase the power of both the signal and the noise present at its input, but the amplifier will also introduce some additional noise.

6. Attenuator (electronics) - Wikipedia

   passive. Electronic symbol. 100 Watt power attenuator. An attenuator is a passive broadband electronic device that reduces the power of a signal without appreciably distorting its waveform . An attenuator is effectively the opposite of an amplifier, though the two work by different methods.

7. Constant-voltage speaker system - Wikipedia

   en.wikipedia.org/wiki/Constant-voltage_speaker...

   Constant-voltage speaker systems are also commonly referred to as 25-, 70-, 70.7-, 100 or 210-volt speaker systems; distributed speaker systems; or high-impedance speaker systems. In Canada and the US, they are most commonly referred to as 70-volt speakers. In Europe, the 100 V system is the most widespread, with amplifier and speaker products ...
