• An approximate scheme for decomposing and reconstructing a continuous-time signal as a linear combination of the B-splines is studied. It is an oversampling discrete-time implementation derived by substituting the multifold RRS functions for the B-splines. The RRS functions are multifold discrete convolution of the sampled rectangular functions. Analysis of the scheme yeilds conditions for the circuit parameters to assure stability and required precision. A design example is presented tht makes the error less than 1% in the supremal norm by the oversampling ratio of 512. Its numerical simulation is also presented.
