The unit impulse response of a system is h(t) = e^{2t}, _{t} 0_{.}
For this system, the steadystate value of the output for unit step input is equal to
A control system has input r(t) and output c(t). If the input is first passed through a block
whose transfer function is a^{2s} and then applied to the system, the modified output will be
