Chapter 3, Problem 3.2P

To determine

(a)

The 75%, 90%, and 95% response time of the given system: $0.4\dot{T}+T=4U\left(t\right)$.

To determine

(b)

The 75%, 90%, and 95% response time of the given system: $\ddot{y}+2\dot{y}+4y=U\left(t\right)$.

To determine

(c)

The 75%, 90%, and 95% response time of the given system: $2\ddot{P}+8\dot{P}+8P=2U\left(t\right)$.

To determine

(d)

The 75%, 90%, and 95% response time of the given system: $5\dot{y}+5y=U\left(t\right)$.
