Signal and System Approximation from General Measurements
Signal and System Approximation from General Measurements
In this paper we analyze the behavior of system approximation processes for stable linear time-invariant (LTI) systems and signals in the Paley–Wiener space $$\mathcal{P}\mathcal{W}_{\pi }^{1}$$ . We study approximation processes, where the input signal is not directly used to generate the system output but instead a sequence of numbers is …
