What amplifies signals on a network?
It is called an amplifier.
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 is a bilinear amplifier?
it amplifies both the incomeing and outgoing signals on CB radios
What amplifies sound waves by as much as 20 times their original intensity?
A microphone and an amplifier with a loudspeaker does this. The microphone converts the soundpressure to electric signals. The amplifier amplifies these signals and the loudspeaker converts back the electric signals to sound pressure. Our ear drums are moved by the sound pressure as a sound field quantity. It is not the sound intensity as an energy quantity.
What amplifies low frequency signals?
An amplifier! Amplifiers are designed for particular band-widths from fractional-Hz, and even d.c., upwards, but that band can be very wide.
What would one use a cell phone amplifier for?
It amplifies the incoming and outgoing signals. This would be used by someone who lived in an area where cell phone reception was poor.
Which device amplifies the incoming signal and noise?
Amplifier repeater
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.
What is meant by amplifier?
An amplifier amplifies the small input signal to a high signal without changing its freqency.
Can a power amplifier amplifies the power?
Question: Can a power amplifier amplify the power? An amplifier can amplify the voltage or the current. Power can be converted to heat.
What does a Car Amplifier do?
It "amplifies" the signal of your stereo so it is louder to hear.
What is an amplifier repeater?
A repeater that does not distinguish between noise and signal; it amplifies both.
