Phase shift 0.5 10 20 Tim A m plitude r atio =b/a This particular graph shows the response of the system: G(S)=3 5s+i to the sinusoidal input of: u= sin(t). The figure shows that the response of the system lags the input changes slightly this lag is known as the phase shift. The ratio of the amplitudes of the input and output sinusoids is known as the amplitude ratio Both the magnitude and the phase shift of a system will change ith the frequency of the input into the system 2022-2-3 32022-2-3 3 - 1 . 5 - 1 - 0 . 5 0 0 . 5 1 1 . 5 0 1 0 2 0 3 0 T im e O u t p u t P h a s e S h ift A B A m p l i t u d e R a t i o = B / A This particular graph shows the response of the system: to the sinusoidal input of: u = sin (t).
