Find gain margin from a transfer function?

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 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 is the difference between transfer function and frequency transfer function?

frequency transfer function deals with transfer in frequency domain, transfer function alone can be referring to any type of transfer in different domain e.g time domain


Formulas of a unity-feedback loop?

In general, the transfer function of closed loop system is (Y/X)=G*K/(1+G*K*H) ----- negative feedback (Y/X)=G*K/(1-G*K*H) ----- positive feedback where G- transfer function of the plant 0r system K - controller H - feedback transfer function Y-output in laplace domain X-reference in laplace domain so the transfer function of the closed loop system with unity feedback is so H=1(unity) (Y/X)=G*K/(1+G*K) ------- negative feedback (Y/X)=G*K/(1-G*K) ------- positive feedback if u couldn't understand notify me... i will improve it


Explain open-loop transfer function of a close system?

An open loop transfer function is the transfer function of a system without incorporating the feedback component. For example, where the closed loop transfer function with unity feedback H(s) = G(s)/(1+G(s)) it can be deduced that the open loop transfer function is Y(s)/U(s) = G(s).


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


What is feed forward transfer function?

product of all transfer function relating input and output when the feedback loop is disconnected from the comparator


Why did you like to transfer in a job?

To gain a wider experience.


What is the Clipping circuit transfer function?

Transfer function is the relationship between output and input of a circuit. In the clipping circuit, the general transfer function is such that the transfer curve Av is less than 1 for passive limiter and greater than 0 to limit the maximum and minimum voltage value.

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.
