<p>PURPOSE:To generate a triangle wave signal whose duty is 100% by extracting a symmetrical triangle wave and the 2nd symmetrical triangle wave being the inversion of the symmetrical triangle wave at each 180 deg.. CONSTITUTION:A transmission circuit 16 is provided, which generates a triangle wave signal VA having a prescribed period and duty and the 1st and 2nd rectangular wave signals VB, VC having an equal period to that of the said triangle wave signal and different amplitude from each other. The signals VA, VB are fed to an AND circuit 17 and fed respectively to signal inverting circuits 18, 19. Then output signals the inverse of VA, the inverse of VB from the circuits 18, 19 are fed to an AND circuit 20 and an output signal VD of the circuit 17 and an output signal VE of the circuit 20 are fed to an OR circuit 21. The output signal VF of the circuit 21 is outputted as the triangle wave signal whose duty is 100%.</p> |
