The effect of the input rs and the disturbance tds on the

Question

The effect of the input R(s) and the disturbance T_d(s) on the output Y(s) can be considered independently of each other because:

a. This is a linear system, therefore we can apply the principle of superposition.

b. The input R(s) does not influence the disturbance T_d(s).

c. The disturbance T_d(s) occurs at high frequency, while the input R(s) occurs at low frequency.

d. The system is causal.
