buffer circuits helpful in overcoming the impedance matching problem.for example if we want to send a signal from one devise to other ,if there is no impedance matching between this two then signal is not transfered.now if we use buffer in between these two devises then the buffer without changing the signal shape or value it simply transffers the signal
A voltage buffer is a circuit that will buffer a source from an output.
the common collector can use as voltage buffer
design and implementation of a buffer circuit using operational amplifier
A buffer amplifier is a type of operational amplifier that amplifies your input signal with a gain of 1 (so your output will be identical to your input, voltage-wise). Buffer amplifiers are used commonly due to having a very high input impedance. This means that loading effects (external factors that your circuit has to deal with) like large currents that could mess with your circuit otherwise, are avoided. A buffer amplifier is often used as the first stage of a circuit because it effectively isolates your circuit from loading effects.
The purpose is to buffer the input for monitoring purposes
noninverting, increased current drive.
Since its input impedance is much higher than its output impedance it is also termed a "BUFFER" for this reason it is also used in digital circuits with basic gates...
A buffer is a means of isolating a signal source circuit from the loading circuit. They are generally needed when the signal source does not have sufficient capacity to deliver the current demanded by the load circuit. If buffers are not used, a problem called input loading results and this may cause the circuit to malfunction or to become damaged. In digital circuits, the buffers reproduce the sequence of 1's and 0's received from one circuit and make them available to another circuit at a higher power level. A buffer is like a non-inverting amplifier with a gain of unity.

Buffers are very useful as impedance matching circuits and as current boosters.They have i/p and o/p voltages same. However they amplify the current. Also they can be used to couple two circuits having different o/p and i/p impedances
Yes; this hard drive has a 16 MB buffer.
No. In the general case, a buffer amplifier is an analog device, but an AND or an OR gate is a digital device. Even in the specific case of a digital buffer amplifier, its still not the same because the digital buffer amplifier has more power available in its output circuit, giving it a higher fanout than just an ordinary AND or OR gate.
A buffer amplifier can be used to transform high input impedence to low output impedence, or vice-versa.

Some advantages of using a floor buffer over mopping are that you will get a very good clean floor. It takes a little less effort to do, and you arnt just pushing dirty water around
