A continuous-time Linear Time-Invariant (LTI) system defined for the purpose of this page will be
$ \ w(t) = 5v(t) $
where v(t) is an input signal dependent on the parameter of time.
The unit impulse response of the system would then simply be
$ \ w(t) = 5\delta(t) $
and the system function H(s) of the system, where
$ \ s = j\omega $
can be determined by taking the Laplace Transform of the system's unit impulse response, h(t).
$ \ L[h(t)] = \frac{1}{T}\int_{0}^{T} h(t)e^{-s}\, dt $
