A linear time-invariant system is described by the following differential equation where y(t) is the system output and x(1)is the input to the system: d'y +4 dy + y(t) = 7+ x(t) dt di? dt What would be the output of the system y(t) if the system is subjected to a 5 Volt step input? Assume that y'(0-) = y(0-) = 0. %3D
