To provide a D/A conversion system and its method in which single or lots of digital data input streams are processed independently of sampling speed applied to each digital data input stream by using a minimum hardware configuration.
The system is made up of a signal input line 400, a re- configuration/resampling device 410, a modulator 430, a D/A converter 440 and a signal output line 460. When a digital data signal or over is in existence as an input to this system, a coupler is included in the system. The re- configuration/resampling device 410 is made up of a sampling element and a polynomial interpolation element. Moreover, the modulator 430 is operated at a fixed frequency set by a phase locked loop 445 independently of the sampling frequency of the digital data signal.
