2. Low-noise amplifier - Wikipedia

   en.wikipedia.org/wiki/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.

3. Tower Mounted Amplifier - Wikipedia

   en.wikipedia.org/wiki/Tower_Mounted_Amplifier

   A Tower Mounted Amplifier (TMA), or Mast Head Amplifier (MHA), is a low-noise amplifier (LNA) mounted as close as practical to the antenna in mobile masts or base transceiver stations. A TMA reduces the base transceiver station noise figure (NF) and therefore improves its overall sensitivity ; in other words the mobile mast is able to receive ...

4. Low-noise block downconverter - Wikipedia

   en.wikipedia.org/wiki/Low-noise_block_downconverter

   Also called a low-noise block, [1] [2] low-noise converter (LNC), or even low-noise downconverter (LND), [3] the device is sometimes inaccurately called a low-noise amplifier (LNA). [ 4 ] The LNB is a combination of low-noise amplifier, frequency mixer , local oscillator and intermediate frequency (IF) amplifier.

6. Instrumentation amplifier - Wikipedia

   en.wikipedia.org/wiki/Instrumentation_amplifier

   Feedback-free instrumentation amplifier is the high-input-impedance differential amplifier designed without the external feedback network. This allows reduction in the number of amplifiers (one instead of three), reduced noise (no thermal noise is brought on by the feedback resistors) and increased bandwidth (no frequency compensation is needed).

7. Lock-in amplifier - Wikipedia

   en.wikipedia.org/wiki/Lock-in_amplifier

   A lock in amplifier uses a multiplier and a low pass filter to compare a reference signal against a noisy signal. A lock-in amplifier is a type of amplifier that can extract a signal with a known carrier wave from an extremely noisy environment. Depending on the dynamic reserve of the instrument, signals up to a million times smaller than noise ...

   In late 1983, HH Electronics launched the Tiger microcomputer, the design of which having been acquired from Tangerine Computer Systems, featuring a Zilog Z80 processor equipped with 64 KB of RAM for running the CP/M operating system, a Motorola 6809 processor with 2 KB of RAM for input/output control, and a NEC 7220 video controller with 96 KB of RAM supporting 80-column, 40-column and ...

9. Naim Audio amplification - Wikipedia

   en.wikipedia.org/wiki/Naim_Audio_amplification

   Naim power amplifiers are given numbers according to their power output into nominal load of 4 ohms. The company's first amplifier, the NAP 160, is a two-channel power amplifier with an output of 60 watts per channel; the NAP 135, which is a one-channel amplifier based on the same design as the NAP 250 rated at 135 watts. A custom-built very ...
