Abstract:
1. A waveform generator for generating an analog signal, comprising: a data changing section which changes an input data sequence, which is a sequence of binary data and which is to be modulated to the signal that the waveform generator should generate, to generate an after-change data sequence such that in the signal to be obtained by MSK modulation, a residual phase obtained by dividing an initial phase of the signal by 2π and a residual phase obtained by dividing a final phase of the signal by 2π are continuous; a waveform generating section which generates basic waveform data representing a waveform corresponding to the signal obtained by subjecting the after-change data sequence to MSK modulation; and an output section which outputs the signal repeating the waveform represented by the basic waveform data, wherein the data changing section includes:
