The gain and bandwidth product is constant only for first order systems. However many complex systems which can be converted and studied as first order, it holds good. This is simple mathematics as in the first order system the frequency appears in the denominator. So if it increases by x times then gain (the modulus of the transfer function) is reduced by x times (approximately).

What is the significance of gain bandwidth product?
To determine the maximum gain a device can extract at that particular bandwidth
What is relationship between gain and bandwidth of an op amp is?
An op amp can have a very large gain, but a limited bandwidth. If you decrease the gain, you can increase the bandwidth.
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 Bandwidth and what's its relation with wavelength?
Bandwidth is the output of some light source, the width of the frequency range which can be transmitted by some element, the gain bandwidth of an optical amplifierthe width of the range of some other phenomenon. It's values may be specified in terms of frequency or wavelength.
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 the relation between bandwith and gain?
The product of bandwidth and gain is constant. If bandwidth increases then gain decreases and vice versa.
What is the relationship between gain and bandwidth?
The basic relationship is that the two together form some kind of constant wherein you cannot have more of one without giving up some of the other. Want more gain? You'll have to work with a narrower bandwidth. Want more bandwidth? You will have to sacrifice some gain to get it.
What is the significance of gain bandwidth product?
To determine the maximum gain a device can extract at that particular bandwidth
Why you are more concentrated on gain-bandwidh product in amplifiers?
Amplifiers all have a gain bandwidth product that varies greatly from device to device. Obviously the bandwidth becomes important at very hi frequency. Is the gain enough for 100 megahertz for a gain of 10? if not you need another amplifier. also the bandwidth product is an indication of how close can one f/b without causing oscillations..
What is relationship between gain and bandwidth of an op amp is?
An op amp can have a very large gain, but a limited bandwidth. If you decrease the gain, you can increase the bandwidth.
What are the effects of negative feedback?
1. less nonlinear distortion, 2. reduction in gain, which is actually in our control 3. since product of bandwidth and gain is constant, reducing gain gives higher bandwidth. 4. more gain stability, as for high gain values, stability is dependent on feedback factor, whic is in our control. 5. can be used to make voltage controlled voltage source, C cntrolled V sources, V controlled C sources and C controlled C sources
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.
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
Which provides a constant bandwidth for the complete duration of message transfer is a?
message switch
Is displaying the attributes of a file delay sensitive or bandwidth sensitive?
it is delay sensitive becoz it doesnt require constant stream for data transfer which is related to bandwidth.
Why do you use feedback?
The voltage gain,input impedance,output impedance,bandwidth etc. are the characteristics of amplifier's. these are more or less constant for a given amplifier. These parameters are required to be controlled. This can be done by using feedback that's why we use feedback.
What is netflow?
Netflow is a Cisco product to analyze network bandwidth usage.
