Abstract :
An off-line or block B-spline interpolation algorithm is modified to an on-line or running form which handles growing data sequences more efficiently. Some loss of interpolation accuracy is suffered with lowpass signals but when the signal is broadband, the increase in interpolation error is negligible while a significant saving in computational effort is obtained.
