PURPOSE:To output all waveforms required for material test by correcting a used variable while continuing signal output even if signals are being outputted, in the function generator using a microprocessor. CONSTITUTION:In the function generator using microprocessor 1, counters 4 and 5 which have a up-down function by entry of a prescribed variable relating to output signals, and pulse generator 6 connected to selector switches 7 and 8 which give input pulse signals to counters 4 and 5 and control lead-in of pulse signals are provided. Then, when the amplitude of a sine wave output is increased, switch 7 is closed to the ''+'' side of counter 4 to increase gradually contents of counter 4; and when contents of counter 4 reach a prescribed value, switch 7 is returned to C1. Next, switch 8 is closed to position a2 or b2 for a proper time to correct the average level of the sine wave into a desired correction value. |
