Harmonic response: TC+c=r 5.3 Joule Jo+ cne o(+Jat, I+ joT Recall that for the first order system we have found the harmonic response by substituting in the transfer function S=10

5.3

Harmonic response: This substitution can be done for any system! C(jO)=C(s) R(0) (o)+2o,(o)+m2 +2 +1 amplitude ratio Phase change C(ja 250 R(jO) 2(=∠C-∠R=m0
