<p><P>PROBLEM TO BE SOLVED: To suppress deterioration in SN ratio while reducing the number of wires connecting two chips. <P>SOLUTION: A first chip 10 comprises a noise shaper 14 for converting second data D2 into 1-bit third data D3 and a PDM transmission circuit 15 which transmits a transmission signal YPDM via first signal wiring L1 and transmits a clock signal YCLK via second signal wiring L2. A second chip 20 comprises a moving average filter 22 for converting the third data D3 into 6-bit data, a clip circuit 24 for outputting 5-bit fifth data D5, and a DEM-DAC 25. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
