Abstract

PURPOSE:To enable to reproduce the contents of an auxiliary memory, by transferring a waveform data which has been stored in the auxiliary memory, to a waveform temporary memory, and D/A converting this data after said transfer has been finished. CONSTITUTION:At all times, each channel A1, A2 executes A/D conversion 2 of an output analog data of an amplifier 1 by operation of a controller 5, and repeats its storage to a temporary storage memory 5. This operation is finished at some point of time, and its end is informed to a CPU7. In accordance with said information, the CPU7 changes over an external bus to a CPU bus, and transfers, in order, a data of a memory to an external auxiliary memory 8. Subsequently, when reproduction of a waveform data which has been recorded in the memory 8 is requested, the CPU8 puts the external bus under the control of the CPU7, and transfers, in order, a designated data of the memory 8, to the memory 4. When said operation has completed, the external bus is shifted to the controller 5, and D/A conversion of a data of the memory 4 is started by a D/A converter 3.
