11. A system is described by the following differential equation: [Section 2.3] d²x dx +2. +3x=1 dt² dt with the initial conditions x(0) = 1, x(0) = −1. Show a block diagram of the system, giving its transfer function and all pertinent inputs and out- puts. (Hint: the initial conditions will show up as added inputs to an effective system with zero initial conditions.)
