no phase shift
A doped fiber amplifier amplifies light in the fiber as a LASER.A semiconductor amplifier is an electronic circuit that amplifies electrical signals.
Common emitter is the only transistor configuration that has an 180 degree phase difference between input and output. Common base and common collector outputs are in phase with the input.***********************************That is incorrect.The output of the common emitter is inverted, there is no phase shift.
It is called an amplifier.
The electric motor does not work on the principle of the amplifier and the digital signals.
An amplifier is an electronic device used to increase the amplitude of electrical signals in sound production.
It is a normal amplifier, fast enough to amplify high frequency video signals. The word "video" means wideband. That's why a video amplifier is used for, for instance, for t.v. signals and in wideband measuring equipment.
It takes the difference between of two input and amplify by the open loop gain of the amplifier or closed loop gain of the amplifier. It is very hard to control open loop gain of 100 Db so it very seldom used
A instrumentation amplifier is a special purpose linear amplifier used to amplify low level signals. These are used in many industrial and medical applications.
sound is made from vibration
A headphone amplifier is a type of audio amplifier. Instead of an amplifier that's designed to push through audio signals to speakers, a headphone amplifier is designed to work with headphones. These are common in devices such as MP3 players.
A RF amplifier is a device for electrically amplifying the power of an electrical signal, typically, but not exclusively, radio frequency signals.
it amplifies both the incomeing and outgoing signals on CB radios
