Does the power amplifier amplifies the power?
the final stage of a power amp is a current amplifier in a bipolar design and a voltage amp in a FET design.
An RF amplifier amplifies the incoming signal by 200 times Calculate the power gain of this amplifier in dB?
If an RF amplifier amplifies the incoming signal by 200 times, the power gain of the amplifier is +25.9 dB. Power is proportional to voltage squared, so the power gain is 400. The decibel scale is 3 times log2 of the power change.
What are the difference between Erbrium doped fiber amplifier and semi-conductor amplifier?
A doped fiber amplifier amplifies light in the fiber as a LASER.A semiconductor amplifier is an electronic circuit that amplifies electrical signals.
What 3 things does an electrical amplifier amplify?
An electrical amplifier amplifies 2 physical quantities according to the transistors used. If a BJT is used it amplifies the current and if a MOSFET is used it amplifies the voltage. Hybrid amplifiers amplify current as well as voltage so in theory , current voltage and power is amplified.
What amplifies signals on a network?
It is called an amplifier.
What is the advantages of instrumentation amplifier?
it is mainly used for increasing the gain of the circuit
What is the main difference between a class 'A' and a class 'B' amplifier?
A class "A" amplifier amplifies the entire waveform, a class "B" amplifier only amplifies the first 1/2 of the wave form. See the images in the related link.
Which device amplifies the incoming signal and noise?
Amplifier repeater
What is meant by amplifier?
An amplifier amplifies the small input signal to a high signal without changing its freqency.
What does a Car Amplifier do?
It "amplifies" the signal of your stereo so it is louder to hear.
What is a bilinear amplifier?
it amplifies both the incomeing and outgoing signals on CB radios
What is an amplifier repeater?
A repeater that does not distinguish between noise and signal; it amplifies both.
