Zusammenfassung:	PURPOSE:To always attain simulation in a synchronous state by storing respectively a waveform data to plural memories, applying frequency conversion to the analog conversion output of one memory, and using the count of a pulse train to access simultaneously the memories. CONSTITUTION:Each waveform data relating to a reference pulse (a), a rotation pulse (b), a needle lift pulse (c), and a turning angle signal (d) is loaded respectively to corresponding RAMS 1-4 via a controller 7. Each data is converted into an analog value by D/A converters 12-15. The output of the converter 15 is subject to frequency conversion by a voltage/frequency converter 20 and its pulse train is counted by a counter 21. Then the controller 7 used the count of the counter 21 as an address to access simultaneously the RAMs 1-4 to extract each data thereby performing simulation. Thus, pulse signals are simulated while being synchronized at all times.
