it is tempting to compare a repeater to an amplifier, but the comparision is inaccurate. according to Forouzan, an amplifier cannot discriminate between the intended signal and noise; it amplifies equally everything fed into it. a repeater does not amplify the signal; it regenerates the signal. when it receives a weakened or corrupted signal, it creates a copy, bit for bit, at the original strength.
a repeater is a regenerator; not an amplifier
a repeater forwards every bit; it has no filtering capability
a repeater connects segments of a LAN
Difference between Amplifier and Repeater 1. Amplifier is used to magnify a signal, whereas repeater is used to receive and retransmit a signal with a power gain. 2. Repeater has an amplifier as a part of it. 3. Sometimes, amplifiers introduce some noise to the signal, whereas repeaters contain noise eliminating parts.
A repeater that does not distinguish between noise and signal; it amplifies both.
A signal repeater is designed to extend the input signal for longer lengths than the original cable design. It encorporates an amplifier to boost the signal.
A bridge acts as "bridge" between two networks or network subnets. A repeater merely strengthens the signal. You can have a repeater that only acts on one wire.
A hub is a multi-port repeater. Therefore, the difference is that a repeater has only 2 ports and a hub has more than two ports. Other than that, they operate identically.
normal amplifier is a mathametical operation analog the computer, magnetic amplifier is sound operation of the signal
A multistage amplifier is composed of several single stage amplifiers.
The amp for audio freq. is a AF amplifier. The RF amp is for radio freqs.
An amplifier is usually stabilized by means of negative feedback. An oscillator is an amplifier which is made unstable by means of positive feedback.
Amplifier amplifies the input signal whereas an Oscillator generates a sinusoidal signal!
In packet networking, a re-generator takes the existing radio signal and boosts it whereas a repeater interprets the data and re-sends it.
Electricians will tell you that a differential amplifier is a type of electronic amplifier that amplifies the difference between two voltages but does not change the particular voltages.
An oscillator will generate a waveform. An amplifier takes a small wave and 'amplifies' it to a big wave.
1.Small signal amplifier can be designed easily using s parameter while large signal amplifier not.
An ordinary amplifier can have high gain but is unstable, drifts, can oscillate, etc. An amplifier with negative feedback has lower gain but is stable, does not drift, won't oscillate, etc.
It has to do with the load on the amplifier, you can't hear the difference.

A cellular repeater is a tiny device used in cellphones in order to maintain a connection. The device works on the same principles as an amplifier and is used to enhance the battery life of the cellphone.
A doped fiber amplifier amplifies light in the fiber as a LASER.A semiconductor amplifier is an electronic circuit that amplifies electrical signals.
differnece between inverting and non-inverting amplifiers
An ordinary amplifier is the one which amplifies the input signal alone.. but an Operational amplifier performs the functions of summing, inverting, differentiation, integrating, division, multiplication etc..of the input signal..
