Question

We are interested in the harmonic forced response of a first-order system with time constant 0.3 s and input u(t) = 5 cos(2t). Calculate the output amplitude.

This graph represents the harmonic forced response of a system. Which response is correct? O The amplification factor is 0.5 and the-phase shift is 0.5 rad. O The amplification factor is 2 and the phase shift is 0.5 rad. O The amplificationfactor is 0.5 and thephase shift is 1.5 rad.on mu O The amplification factor is 2 and the phase shift is 1.5 rad.
