Consider we have a system like this.

Where T[sub]d[/sub](s) is the disturbance, and N(s) is the noise.

How would shall i define the effect of the disturbance and noise for the overall system??

I am bit confused on how I should define it, and i would be very grateful if someone could explain how they define the equation which defines the effect on Y(s).
