<p>PROBLEM TO BE SOLVED: To easily avoid a slip without changing the readout order of readout addresses by writing input data to a storage means according to write addresses, reading the input data out according to the readout addresses, alternately placing read and write means in operation, and selecting and outputting input data read out by a read and write means in operation. SOLUTION: Memories 10-1 and 10-2 of systems 1 and 2 are placed in operation by turns, in with of frames, by using input frame pulses and the memory 10-1 of the system 1 are placed in writing and reading operation by a choice 1 and a choice 2 for the 1st frame of input data. By using different memories for each frame, both the write and read addresses overlap with each other, even at the place where the reading of a last frame as a slip occurrence place and the writing of a next frame overlap with each other, so that a slip can be avoided without varying a WR-RD address initial phase difference and the memory capacity and changing the readout order of RD addresses.</p> |
