The root word "ample" means abundant, having lots of something, as in, we had ample food to eat at the feast. To amplify means to make something more ample. So when it comes to sounds, if you take a faint sound and make it louder, you are amplifying it. That is what an amplifier does.

∙ 9y agoThe description "operational amplifier" is abbreviated to "op-amp". In certain circuit arrangements it can be used to do specific tasks beyond mere amplification, eg integration or differentiation.

What is self saturated magnetic amplifier?
an amplifier which is self saturated is called self saturated magnetic amp
Am amplifier that inverts the signal between input and output is called a what?
common emitter
What is one common application of a cc amplifier?
current amplifier
The use of swamping resistor in differential amplifier?
the use of swamping resisters in amplifier is in order to protect the amplifier from high temperatures
What is a 1 channel amplifier?
A mono amplifier. You need two for stereo.
Why is an operational amplifier called so?
Originally such an amplifier did mathematical functions.
What is self saturated magnetic amplifier?
an amplifier which is self saturated is called self saturated magnetic amp
What amplifies signals on a network?
It is called an amplifier.
What are the factors which affects amplifier stabilization?
The main thing you need to look at to determine the stability of an amplifier is something called the K-Factor. This measures the oscillation of your amplifier in steps.
Antenna is a Active or passive devices?
it depends on existing amplifier or not , if after antenna there's an amplifier it called active else it called passive which less sensitive that active .
What is wideband amplifier?
A wideband amplifier is an electronic circuit providing constant amplification with a ratio of its low corner frequency to its high corner frequency of more than an octave. The widwband amplifier is complementary in concept to "audio amplifier" (20Hz-20KHz) and "video amplifier" (15KHz to 4.8MHZ). The "opposite" concept is the narrow-band or tuned amplifier. There's a new wideband amplifier technology called PowerBand from TriQuint Semiconductor. end-
What are subtractor op amplifier?
The circuit that takes the difference of two signals is called a subtractor. It is made by connecting an inverting amplifier to a two-input inverting averager.
Why RC coupled amplifier is called audio amplifier?
Because radio control relies on different frequencies. Since frequencies are involved in the process, an audio amplifier can be used to amplify alternating currents (currents that change), and it does the same job.
Who is more gain amplifier cascaded amplifier or darlington amplifier?
Darlington amplifier has more gain when compared to cascade amplifier .
Am amplifier that inverts the signal between input and output is called a what?
common emitter
What is the electronic device that's used to increase the strength of the signal fed into it called?
Amplifier
what are the types of biological amplifier?
1.differential amplifier 2.operational amplifier 3.instrumentation amplifier 4.chopper amplifier 5.isolation amplier
