Q. For given asymptotic Bode plots.
(a) Find ¯H1, ¯H2, and ¯H3 at ω = 5 rad/s.
(b) At what angular frequency ω is the magnitude of ¯H4(jω) one-half of the magnitude of ¯H4(j5)?
(c) Determine the angular frequency at which H6(ω) is 0 dB and the angular frequency at which θ6(ω) = -180°.
(d) Let H5(s) = V2/V1. For v1(t) = 0.1 cos 20t, find the steady-state value of v2(t).
