PURPOSE:To simplify circuit constitution by arranging a register at the output of a ROM and by feeding its output to the address of the ROM and also supplying it directly to the address of an audio signal memory, etc. CONSTITUTION:An audio signal modulated with an audio switch 12 is inputted to a memory 18 through an encoder 16. Signal information sampled with a signal switch 13 is inputted to a memory 19 through a delay circuit 17. On the other hand, the output of a ROM20' stored with a program realizing channel conversion is inputted to addresses of memories 18 and 19, and the ROM20' through a buffer register 36. Then, the latter half of the time slot of each channel is set as a writing time and the former half as a reading time; inputs are written in the memories 18 and 19 specified at random by an address sequence corresponding to the inputs, and read from the addresses of the specified memories 18 and 19 by another address sequence to convert the time slot. |
