What are advantages and disadvantages of multistage amplifier?
to amplify a small signal to sufficient level,so that it can travel to a large distance from first stage till the last stage
How expensive is a set of Crown amplifiers?
Crown amplifiers differ in price range depending on what kind you want. If you were to buy a new, small crown amplifier it would cost around 1000 dollars while a new, larger crown amplifier would cost around or above 2000 dollars. Crown amplifiers that are not new will likely cost less than a thousand depending on how complex and large the amplifier is.
Differentiate between small signal and large signal amplifier?
The amplifier is supposed to be an electronic circuit. Electronic circuits are nonlinear circuits, which may be modeled in the time domain by means of nonlinear differential equations and nonlinear algebraic equations. The kernel of the solution of the nonlinear equations is the solution of a linear equation system i.e. the nonlinear components and couplings are approximated with linear relations valid for small signals. Iterations are performed until the laws of Kirchhoff are fulfilled. The instant set of linear equations is the small signal model for the amplifier. If the amplifier is excited with a dc power source it assumes an active state called the bias point or quiescent point. If the relation between the input and the output signals of the amplifier is measured to be (almost) linear in the bias point then we assume a small signal amplifier with time independent bias point else we assume a large signal amplifier.
Where can one purchase a ear amplifier?
A ear amplifier can be a useful device if one is in a noisy situation and has difficulty hearing what one wishes to hear. Digital ear amplifiers can be bought at Specsavers, despite the name of the shop perhaps suggesting otherwise.
What is the definition of amplifier?
If you are speaking of the radio amplifier, it takes the low powered signals from the radio and increases them for output to the speakers. Amplifiers usually have some provision or internal programming for splitting the signal so lower frequencies go to subwoofer and midbass speakers while higher frequencies go to tweeters.
What is meant by the term large signal amplifier?
power amplifiers are the amplifier which raise the power levels of the signal.the power amplifier may also defined as a device which converts dc power to ac power and whose action is controlled by the ac input signal. Power amplifiers are also known as "LARGE SIGNAL AMPLIFIER".the term large signal arises because they use large part of load line for their operation,but the small signal amplifiers are use only 10% load line for their operation.

Whats the main difference between small signal amplifier and large signal amplifier?
1.Small signal amplifier can be designed easily using s parameter while large signal amplifier not.
How does a stereo power amplifier work?
Quite well. But what kind of amp? In general, the amp takes a "line level" signal (left and right channel) and puts it through a series of amplifiers to make the signal bigger (amplify it). This is an increase in what is called the "gain" of a given stage or of a series of stages. Small signals drive the "control" circuit of the semiconductor devices, which are the amplifiers themselves, and this causes large swings in the output voltage of the stage (giving the amp gain). After a few of these, the signal is sufficiently amplified and can be used to drive a pair of speakers.

Where can one purchase a distribution amplifier?
A distribution amplifier can be purchased on-line from the manufacturer or other website stores that stock this product. Distribution amplifiers can also be purchased at large electronic retail stores.

Difference between amplifier and power amplifier?
Voltage amplifiers are genrally used to amplify voltage signals to a certain db and amplification is a linear process. In power amplifiers it is not required to amplify voltage it is not significant and genraly equal to input voltage. It is significantly used to produce a large current at the output.

What is difference between ac and DC amplifier?
AC amplifiers are used to amplify AC signals and use components that handle large voltage values. DC amplifiers are used to amplify DC signals which use small powered electronic devices.
What are the classifications of large signal amplifier?
LSA means that your amplifier will follow its specs also if you ask it to perform a large signal transition (ie fast output voltage change from rail to rail). In fact, bandwidth performances are given for small signal variation (a transition where output voltage variation is much smaller than rail to rail ).
What is buffer amplifier and its applications?
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.
