摘要: Physical systems typically evolve continuously whereas modern controllers and signal processing devices invariably operate in discrete time. Hence sampling arises as a cornerstone problem essentially all aspects of science. This paper reviews various signals systems. We argue that careful consideration must be given to obtain meaningful results when interconnecting physical system computer for the purpose data storage, processing, or control. also take opportunity dispel several common misconceptions about sampled-data
