It depends on the signal you are trying to receive.
For instance, the AM frequency band lies around 500KHz to 1700kHz. Lets say you have a tuned amplifier such that the resonant frequency was set roughly in the middle of that band at 1000kHz (1MHz). AM radio stations typically space out their broadcasts 9-10kHz.
So if Q=f_resonant/f_bandwidth
the Q of a tuned amplifier with a bandwidth of 10kHz (which would be decent, maybe a little spill over), would be:
Q=1Mhz/10kHz
Q=100
The higher the Q, the greater the selectivity. Too high be a bad thing too.

Why consider only 3dB for bandwidth calculation?
3dB of gain rolloff is a linear reduction of gain by a factor of 2. That makes it a good reference point.
Is an AudioBahn A800t a good amplifier?
yes it is you need to have good tune it and it pump out sound clean
What class of amplifier conducts for 100 percent of a cycle?
Class A. Wikipedia has a really good set of data to give you a start on understanding amplifier classes.
Mixer circuit used in Amplitude demodulation?
The mixer circuit in a superhetrodyne receiver, used for both AM and FM receivers, is a local oscillator that is tuned to 455 KHz away from the desired signal (AM), or 10.7 MHz away from the signal (FM), followed by a broad band summing amplifier or, more typically, just a pair of diodes, resulting in shifting the RF signal into the IF range. By Fourier analysis, when you add two signals, you get four results, each signal, their sum, and their difference. The IF strip following the mixer, a steep skirt bandpass filter, is tuned to the difference, providing the selectivity necessary for good reception.The preceding RF stage is a semi broad band, partially tuned, bandpass tank/amplifier circuit that simply enhances the input signal, providing sensitivity instead of selectivity.
Can anyone suggest how can you choose amplifier and speakers?
you need to choose speakers according to the power supply of amplifier, so that the amplifier can wrok. Besides, to create good sound effect, you need to take your room area into consideration, if the room is small, amplifier and speakers with high power is not necessary. You can visit website of Unify company, they have many packages for amplifier and speakers, hope it can help somehow.

Is high bandwidth good or bad?
yes,obviously its good to have high bandwidth....according to technical feild
Does a powerline router give you good bandwidth?
They do give you higher bandwidth capabilities for your networking.
Is dedicated bandwidth a good investment?
That would depend on how much data bandwidth one is working with. If a person is hosting content for a website that is very popular then yes dedicated bandwidth is a good investment.
What is the theory of voltage series feedback amplifier?
In a Voltage Shunt feedback Amplifier, the feedback signal voltage is given to base of transistor in shunt through a feedback resistor.This Shunt connection decreases the input input impedance and voltage feedback decreases the output impedance. In this amplifier input is current and output is voltage. Thus Transresistance is stabilized.Input and Output impedances are reduced by a factor of 'D'(desensitivity factor). Advantages: 1)Gain independent of device parameters. 2)Bandwidth increases. 3)Noise and non-Linear distortion decrease. 4)Prevents Loading effect. 5)Acts as good source for the next stage.
Where is a good place to mount a car amplifier?
You can mount your car amplifier in the back floor or in the trunk.
What brand of amplifier should be avoided for lack of quality?
Neuhaus T-2 Amplifier is not so good.
Why is a common collector used in the last stage of the amplifier?
becoz it gives good gain which is necessary for an amplifier.
Acquiring Bandwith Monitors?
Bandwidth monitor pro is a good bandwidth monitor to use. It is available at www.bandwidthmonitorpro.com/ and also CNET.com
Why do poorly tuned engines not get good gas mileage?
Poorly tuned engines do not get good gas mileage because they are not running efficiently. When an engine is not tuned properly, it may not be burning fuel as effectively, leading to wasted energy and decreased fuel efficiency.
Are there powered car speakers or do you absolutely need an amplifier?
You should get a amplifier if you want good sound quality out of your speakers.
What important factors should I consider when buying an amplifier for my car?
There are a bunch of important factors to consider prior to buying an amplifier for a vehicle. Primarily, you must decide what the amplifier will be primarily used for. If the amplifier will be used for powering subwoofers it would be good to consider the bridged or mono capabilities as well as ohm ratings of the amplifier as well as the draw, or amount of power the amplifier will pull from the car's electrical system. The most important factor in considering an amplifier for powering subwoofers is probably output watts, which will determine the amplifier's power to the speakers and the amount of bass to be transmitted. If the amplifier is to be used to power mid or high range speakers, a multi channel (four or more) amplifier should be considered because of the ability to run multiple sets of speakers or component sets off of the different channels of the amplifier. The considerations inherent to the subwoofer amplifier are also present including watt ouput and power draw, but when selecting a multi cha
