the first amplifier was made in the year 1909. this was the audio amplifier
of vacuum tube type.
Lee DeForest it was a tube amp, not a solid state amp. Some time between 1905 and 1915 not sure the exact date.
The average amplifier is 60 to 200 amps.
The horizontal and vertical amplifier in the cathode-ray oscilloscope are deflection plates. The horizontal amplifier causes the beam to be deflected horizontally at a rate that is uniform. The vertical amplifier causes the beam to deflect vertically.
A microphone is usually connected to an amplifier.
A common base NPN amplifier is used for high frequency applications as the base minimize oscillations at high frequency, separates the input and output. In a common base NPN amplifier the voltage gain is high, relatively low input impedance and high output impedance compared to the common collector.
input. The microphone gives a signal to the computer/radio/whatever you're using. it is input because when you speak into it,it gets in the amplifier and the amplifier processes it to came out as sound through the speaker
The sound amplifier was invented by Lee de Forest.
The Peavey 5150 amplifier, made by the Peavey Electronics Company, is a very specialized all-tube guitar amplifier originally made for Eddie Van Halen.
no, a subwoofer is not a amplifier a subwoofer is actually a speaker that is made for bass. an amplifier is what helps the subwoofer work and sound properly when you install a audio system in your automobile or home.

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.
Darlington amplifier has more gain when compared to cascade amplifier .
1.differential amplifier 2.operational amplifier 3.instrumentation amplifier 4.chopper amplifier 5.isolation amplier
current series feedback amplifier=series parallel feedback amplifier or voltage to current amplifier,or TRANS CONDUCTANCE AMPLIFIER.
Selective amplifier is an RF amplifier which selects particular frequency and amplifier so it can operate at fixed frequency.
A voltage amplifier does not have to supply significant current bur a power amplifier does.
In audio look at an amplifier. It will be always a voltage amplifier.
