magnitude response across any two points in simulink model

[pankaj jha]

hello everyone!!!
I have a model in simulink. I wish to get the magnitude response (frequency response) between the input and output.
Can anyone tell the steps i should to take get it?????

Can't you just put a spectrum scope??
Sorry, I don't know exactly what you mean...

Use a very short pulse as input stimulus (delta) and compute the spectrum of the output.
P.S. normalize the result by the pulse area
