First find the phase crossover frequency and then use that back into the magnitude of the transfer function.Then the gain margin is the reciprocal of that magnitude.

What is the total brightness gain of an image intensifier with a flux gain of sixty whose input phosphor is ten inches and whose output phosphor is one inch?
6,000 (10/1)squared X 60 =6,000 brightness = minification gain x flux gain minification gain = input divided by output squared
What does gain mean in a math problem?
Gain means to subtract in a math problem because if you were doing a math problem and it said to gain (loose) 9-8=1 so that would be your answer
Where do you find the missing pieces of the statue on furry-paws?
You can't find them all together, but notifications will come up saying " You found this weird object" or something like that. You can also buy them off of peoples shops. They sell them once in awhile. It isn't something you find everyday, but once in awhile you will find one. There are 7 pieces, and once you get them all you go into the cave, pick a dog, and either gain or decrease exp, and stuff like that. I hope this helped you out.
How many minutes of daylight do you gain each day in Jan?
Depends on your latitude, but daylight gain is at a minimum after the winter solstice dwell point ( northern hemisphere) up to maximum daily gain at the spring equinox, gain per day then falls to 0 at the summer solstice dwell point, then this trend is reversed down to the winter solstice, completing the cycle. The graph of daylight hours in say england, resembles a sine curve.
If the gain of the open loop system is doubled then gain margin will become?
gain margin becomes half
What is difference between transfer function and gain?
Gain is also taken as Laplace transform of output to Laplace transform of Input . for example voltage gain calculation , it is not necessary to make the energy will be zero in L and C ( if present in the given circuit). But in case of Transfer function to avoid the system dynamics , we have to make the inductor and capacitor energy will be zero as initial condition = 0
What should be the phase margin and gain margin For stability?
A very high gain margin or phase margin produces stable feedback systems, however they may be sluggish in operation. If the gain margin is close to unity of the phase margin is close to zero, the system will be highly oscillatory and produce overshoots with large amplitudes that take a while to settle. Having a gain of 6 dB or phase margin of 30 - 35 degrees will give you a relatively stable system. However there exists cases where this may not be so. :-)
Formulas of a unity-feedback loop?
The formulas of a unity-feedback loop are: Closed-loop transfer function: This is the ratio of the output of the system to its input in the closed-loop configuration. It is calculated by dividing the open-loop transfer function by (1 + open-loop transfer function). Closed-loop gain: This is the gain of the system in the closed-loop configuration and represents the amplification of the input signal in the system. It is calculated by multiplying the open-loop gain by (1 + open-loop gain). Closed-loop bandwidth: This is the frequency range over which the system can effectively respond to input signals in the closed-loop configuration. It is usually determined by the pole locations in the system's transfer function.
Why did the federal reserve try to regulate margin loans and why were it's efforts only partly successful?
The Federal Reserve tried to regulate margin loans to gain control of margin requirements for stocks bought on margin. Regulation T gives the Federal Reserve the authority to change the percentage of the initial margin requirement for margin stock. Since 1974 the Federal Reserve has not deemed it necessary to adjust the margin requirement
What is the difference between driving point function and transfer fuction?
consider a two port network. if u take the ratio of output of one port either current or voltage/ input of other port either voltage or current, if it is same parameter ie. V2/V1 then we call it as transfer function or gain also. V1 is the input port voltage and V2 is the output port voltage. In s domain also we can call it as transfer function, and also not necessary restricted to s-domain only. Suppose if is of different parameter ie. I1/V2 we can call it as reverse transfer admittance function but thing is to note the presence of 'transfer' term. At the same time the ratio of parameter current or voltage of the same port we call it as driving point function. It can be Admittance function ie. I1/V1 or Impedance function ie. V1/I1
Why did you like to transfer in a job?
To gain a wider experience.
What is the significance of transfer function of a system?
It tells you what the system does to the input signal(s) to generate the output signal(s). The transfer function can be expressed in either the time domain or the frequency domain, depending on whichever is easier to deal with in the application.
What is a programmable gain amplifier?
A programmable gain amplifier (PGA) is a electrical circuit that allows the controller (user, machine) to adjust its transfer function so as to provide larger or lesser voltage gain. Usually it is a simple circuit, using an operational amplifier with negative feedback. In the negative feedback loop, several resistors and switches open and close, in order to achieve the desirable gain.
What is an antimorph?
An antimorph is a gain of function mutation which acts in opposition to the normal gene's function.
Why gain bandwidth product is constant?
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 Primary function of the common collector amplifier?
current gain
