On the use of the residue theorem for the efficient evaluation of band-averaged input power into linear second-order dynamic systems

An alternative to numerical quadrature is proposed to compute the power injected into a vibrating structure over a certain frequency band. Instead of evaluating the system response at several sampling frequencies within the considered band, the integral is computed by estimating the residue at a few...
