EC > GATE 2014 SET-4 > Laplace Transform
A causal LTI system has zero initial conditions and impulse response h(t). Its input x(t) and output y(t) are related through the linear constant-coefficient differential equation
d2y(t)/dt2 + α(dy(t)/dt) + α2y(t) = x(t).
Let another signal g(t) be defined as
If G(s) is the Laplace transform of g(t), then the number of poles of G(s) is _____.
d2y(t)/dt2 + α(dy(t)/dt) + α2y(t) = x(t).
Let another signal g(t) be defined as
