WitrynaN.B. Although this method is a very simple one, it generally gives poorer results than the two others, i.e. the bilinear transform and the impulse-invariant method. One disadvantage is that if the prototype continuous filter has no zeros then the discrete ‘equivalent’ will have no zeros. This is not true with the two other conversion methods. http://www.vibrationdata.com/ramp_invariant/force_ramp_invariant.pdf

WitrynaThe impulse-invariant mapping produces a discrete-time model with the same impulse response as the continuous time system. For example, compare the impulse … WitrynaThe two most common of these methods are the impulse-invariant method and the step-invariant method. They preserve the shape of the impulse (or step) response of the analog system by defining the desired digital system as the one whose impulse (step) response is a sampled version of the corresponding analog impulse (step) …
