ABSTRACT:
A plurality of serial-in/parallel-out shift registers(9,11,13,15) can input n-tuple speed data (where n is a positive integer) in series in synchronism with an n-tuple speed sampling clock sequentially via input ports(2a,2b) to store them within one period of an M.multidot.n-tuple speed frame clock (where M is a positive integer and M.gtoreq.2), and then output the n-tuple speed data in parallel every period of the M.multidot.n-tuple speed frame clock. A plurality of parallel-in/serial-out shift registers(17,19,21,23) can input in parallel the n-tuple speed data which are output from the plurality of serial-in/parallel-out shift registers(9,11,13,15) respectively, and then demodulate the n-tuple speed data into M.multidot.n-tuple speed data in synchronism with an M.multidot.n-tuple speed sampling clock and outputting the M.multidot.n-tuple speed data in serial.
