A sampling function waveform data generating device for fast generating data on a waveform approximating a sampling function with a simple circuit structure. Data on a waveform of a step function is outputted from a memory (20). A first digital integrating circuit (30) integrates the data on waveform of the step function and outputs data on a waveform of a broken-line function. A second digital integrating circuit (40) integrates the data on the waveform of the broken-line function and outputs data on a waveform approximating a sampling function. The outputted sampling function is a finite support function that is differentiable once, takes on 1 in sampling position t=0, 0 in all the other sampling positions, 0 in the ranges t<-3 and t>+3, and a value other than 0 in the other range, and converges to 0 in sampling positions t=+/-3.
