A system has transfer function
. If a sinusoidal input of frequency ω is applied the steady state output is of the form
. If a sinusoidal input of frequency ω is applied the steady state output is of the form
K1 K2 (1 + jω/T)
K1K2/jωT
Answer: Option
Explanation:
For sinusoidal input jω replaces s in the transfer function.
