2. Bridged and paralleled amplifiers - Wikipedia

   en.wikipedia.org/wiki/Bridged_and_paralleled...

   On audio chat forums, some hobbyists claim that operating an amplifier's stereo pair in bridge mode will deliver four times the power of one of the pair's channels. Given an equivalent load, power delivered is proportional to the square of the voltage, and bridge mode operation doubles the voltage presented.

3. RF power amplifier - Wikipedia

   en.wikipedia.org/wiki/RF_power_amplifier

   A radio-frequency power amplifier (RF power amplifier) is a type of electronic amplifier that converts a low-power radio-frequency (RF) signal into a higher-power signal. [1] Typically, RF power amplifiers are used in the final stage of a radio transmitter , their output driving the antenna .

4. Isolation amplifier - Wikipedia

   en.wikipedia.org/wiki/Isolation_amplifier

   Amplifiers providing both input-to-output and channel-to-channel isolation. This is the purest form of isolation, and the option that should be considered for nearly all applications. Multi-channel instruments that employ it are immune to inconsistent common mode voltages on any combination of channels within the limits of the amplifiers.

5. Bi-amping and tri-amping - Wikipedia

   en.wikipedia.org/wiki/Bi-amping_and_tri-amping

   A single amplifier can usually power a woofer and a tweeter only through a post-amplifier crossover filter, which protects each driver from signals outside its frequency range. Bi-amping of speakers requires double the channels of amplification and can be accomplished using two ordinary amplifiers in either a vertical or horizontal arrangement.

6. Oscilloscope - Wikipedia

   The X-Y mode also lets the oscilloscope serve as a vector monitor to display images or user interfaces. Many early games, such as Tennis for Two, used an oscilloscope as an output device. [12] Complete loss of signal in an X-Y CRT display means that the beam is stationary, striking a small spot.

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 ...
