Abstract
A sampling function generator capable of providing continuous output corresponding to a sampling function. The sampling function generator comprises a B spline function generation circuit delay circuits and inverting amplifiers and and adding circuits and The B-spline function generation circuit continuously produces signal waveforms according to a third order B spline function. After delayed by predetermined time or attenuated to 1/4 amplitude and inverted, the signal waveforms are combined in the adding circuits and to form a signal waveforms of a sampling function that is differentiable once over the range and has values of local support.
