WebThe 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) response.

WebJul 2, 2024 · A precise definition of what is meant by an invariant curve is crucial here. If it is as above, that you fix a time, take the corresponding homeomorphism, and any invariant set shaped as curve is an invariant curve, then it does not hold. But if you, eg. require the curve to be invariant for all time-maps or the flow itself, then it is correct.
