<P>PROBLEM TO BE SOLVED: To suppress generation of phase distortion in conversion into an analog signal by reducing influences of jitter received by a transmission signal transmitted on a transmission line. <P>SOLUTION: A high frequency unit 22 demodulates a transmission signal resulting from modulating a carrier wave using a digitized waveform signal stream transmitted from a transmission source. A position determination unit 50 determines a position of another digitized waveform signal in demodulated digitized waveform signals, in a reference timing represented by a reference timing signal having a frequency of multiples of an input timing signal specifying a timing of inputting to a processing unit 24 for one digitized waveform signal in the demodulated digitized waveform signal stream. Based on a value of the other digitized waveform signal and the position of the other digitized waveform signal determined by the position determination unit 50, an interpolation unit 44 calculates an interpolated digitized waveform signal in the timing of inputting to the processing unit 24 for the one digitized waveform signal and supplies the calculated signal to the processing unit 24. <P>COPYRIGHT: (C)2008,JPO&INPIT |
