What is Bandwidth of RF amplifier?
That depends on its purpose. Some examples:RF amplifier in IF stage of AM radio: 10KHz.RF amplifier in TV set: 6MHz.RF amplifier in IF stage of FM radio: 200KHz.An RF amplifier in a military RADAR set will probably have very narrow bandwidth to reduce jamming possibility, but wide enough to allow for doppler shift of targets.
What is the importance of the quality factor Q of a tuned amplifier?
If quality factor is greater then bandwidth will also greater
Need of multistage amplifier?
The Gain provided by the multistage amplifier is greater than the gain of single stage amplifier. The gain of the two stage amplifier is the product of the gain of the individual stages.
What is Full power bandwidth of an operational amplifier?
everyone, As far as I know the Full power bandwidth is the output bandwidth of the signal when it is made to obtain the max power from output suppose max output voltage is +/- 10 V as prescribed in the data sheet and the slew rate is 600V/u sec , then the full power bandwidth will be 600/(2*pi*10) that is 9.548 MHz
What is the configuration of cascade amplifier?
In a cascade amplifier, two identical or non identical amplifiers are cascaded ,i.e., connected in series through a capacitor. They are mostly common emitter amplifiers that are cascaded together.The final gain of the cascaded amplifier is the product of the first amplifier's gain and the second amplifier's gain. However, the bandwidth of the cascaded version becomes lesser than the individual gains.
What is effect on bandwidth due to positive feedback amplifier?
bandwidth decreases
If bandwidth of amplifier reduced then thermal noise in amplifier?
thermal noise willbe reduce
What is the purpose of determining frequency response?
frequency response curve helps us to find the bandwidth of particular amplifier circuit. Bandwidth is the range of frequency at which the amplifier works better....

Working of Rc coupled amplifier using negative feedback?
As gain increases bandwidth decreases.

How does bandwidth of a current series feedback amplifier change with frequency?
Bandwidth does not change with frequency. Bandwidth defines (part of) how the response of a circuit changes with frequency. Other things that define how the response of a circuit changes with frequency are: phase shift, roll-off rate, linearity of the passband, etc. but bandwidth ignores these.
What is the use of finding the bandwidth of an amplifier?
A: Any amplifier will have greater band with if operated open loop. It will also be very unstable so negative feedback is implemented for that reason. There is some drawback when feedback the band width of the amplifier decreases, So is important to find out if the amplifier when stable will it have the band width required
What Advantages of double tuned amplifiers over single tuned amplifiers?
The primary advantage of a double tuned amplifier, such as, an amplifier with a tuned circuit on the input and the output, is narrow bandwidth. Another advantage to the circuit is impedance matching with the previous stage, etc. And last but not least your double tuned amplifier will have more gain for electrons spent getting the job done. In our battery operated everything world that is an important design factor.
Why won't a satellite TV in-line amplifier boost a DTV signal in a fringe area?
Most likely it's because the satellite amplifier doen't have the bandwidth or frequency range to cover the DTV signal.
Will gain increased bandwidth also increase to some extent after which stability decreses?
A: The question not very well formulated. But i will try to answer it. Any amplifier will have the maximum gain and the wider bandwidth when it is in a open loop situation. As feedback is added both the gain and the bandwidth will decrease but stability will increase
