Find the impulse response function of a system whose transfer function is given by (a) (G(s)=1 /(2 s+1)) (b) (G(s)=1 /left(2 s^{2}+3 s+1 ight)) (c)

Find the impulse response function of a system whose transfer function is given by

(a) \(G(s)=1 /(2 s+1)\)

(b) \(G(s)=1 /\left(2 s^{2}+3 s+1\right)\)

(c) \(G(s)=1 /\left(s^{2}+4 s+4\right)\)

(d) \(G(s)=1 /\left(s^{2}+9\right)\)

(e) \(G(s)=(5 s+4) /\left(s^{2}+5 s+4\right)\).
