PURPOSE:To shorten the time required for the multiplication processing essential to a generator to obtain all waveforms required for material test by providing a circuit having a multiplication function in the function generator using a microprocessor. CONSTITUTION:In the function generator using microprocessor 1, multiplication circuit having a multiplication function is provided besides this processor 1, and a step where a multiplication command is executed is provided in the program of processor 1. Then, after multiplier A and multiplicand B are outputted from memory 2 and are converted to analogue signals by D/A converters 4 and 5, these signals are outputted after M=AXB operation in analogue multiplication circuit 6. By this constitution, the multiplication time is shortened to output signals of a desired waveform simultaneously with leading-out of a reference waveform. |
