WitrynaI understand that the impulse response of the system is the inverse Laplace transform of the system without multiplying the system by the frequency domain source (since the impulse function transforms to 1 in frequency domain, so 1*system = system). When you say "H (1/s)" does that mean "H of 1/s"?

WitrynaThe obvious approach is to determine the ideal impulse response and then to take a finite number of terms symmetrically disposed about its midpoint. This would produce ripples of increasing height near an abrupt change in the amplitude, and to reduce these the ‘Window method’ has been produced. Essentially it involves the following steps: 1.
