1 1 vote A linear, time-invariant, causal continuous time system has a rational transfer function with simple poles at $s=-2$ and $s=-4$, and one simple zero at $s=-1$. A unit step $u(t)$ is applied at the input of the system. At steady state, the output has constant value of $1.$ The impulse response of this system is $[\exp (-2 t)+\exp (-4 t)] u(t)$ $[-4 \exp (-2 t)+12 \exp (-4 t)-\exp (-t)] u(t)$ $[-4 \exp (-2 t)+12 \exp (-4 t)] u(t)$ $[-0.5 \exp (-2 t)+1.5 \exp (-4 t)] u(t)$ Control Systems gate2008-ec continuous-time-signals transfer-function linear-time-invariant-systems impulse-response + – admin 275 views answer comment Share Follow Add Sync Questions Print 0 reply Please log in or register to add a comment.
