PROBLEM TO BE SOLVED: To correctly and easily instructs paths to be followed to a plurality of demodulators. SOLUTION: The digital data demodulators which follow respective paths are placed in mutually independent operation and provided with PN code generators 313, 323, and 333 having ROMs 61 stored with PN codes respectively. Then a control part monitors a ROM address latched by an address latch circuit 64 to generate a PN address relative value, an address adder 63 adds a PN address relative value to a basic address generated by an address counter 62, and the addition address is supplied to the PN code ROM 61 to generate a PN code. |
