A simple scheme of decomposition and reconstruction of continuous-time signals by B-splines
Koichi Ichige, M. Kamada, R. Ishii · 1998
An approximate scheme is proposed for decomposing and reconstructing a continuous-time signal as a linear combination of the B-splines. It is an oversampling discrete-time implementation derived by substituting the multifold RRS functions for the B-splines. Its analysis yields conditions for the circuit parameters to avoid instability and overflow, and to meet required precision. A design example and its numerical simulation are also presented.
