A device used to make an instrament louder, usually an electric guitar. Sound signals have a certain amplitude behind them (power). If the signal is week, it is difficult to hear and transmit. Therefore, you need an amplifier to add power to a signal in order for it to be heard and transmitted.
Amplifiers are used to strengthen analog signals. Analog signals become weaker after travelling a certain distance,they need to be amplified so that the data is not lost on the way and reaches intact.
It is called an amplifier.
amplifier will strengthen da small input signal n amplifies it
Regenerative Repeater is used for the PCM (Pulse code modulation ) it amplifies the signal because the effect of the channel over the signal .
More wire in a smaller space. Each turn amplifies the induction voltage in the same way a string of series connected batteries multiplies voltage.
Hearing amplifies can be purchased from a variety of retail locations and online stores. Sharper Images, Siemens, and Amazon, for example, each sell this item.

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.
It amplifies a persons voice.
resonator
The number of times it amplifies the image.
Amplifier repeater
It "amplifies" the signal of your stereo so it is louder to hear.
A doped fiber amplifier amplifies light in the fiber as a LASER.A semiconductor amplifier is an electronic circuit that amplifies electrical signals.
