Title:
WAVE SHAPE PROCESSING CIRCUIT FOR PULSE GENERATOR
Document Type and Number:
Japanese Patent JPH04258715
Kind Code:
A
Abstract:
PURPOSE:To dissolve the trouble that response processing in a motor control circuit is made impossible because of the high speed revolution, by generating the shift quantity signal having the long cycle independently of the duty ratio of the signal outputted from a pulse generator. CONSTITUTION:Each trigger signal Q1 is generated from both the edges of the rising-up and falling-down of an A phase pulse signal E1 outputted from a pulse generator is generated, an the trigger signal Q1 is divided into trigger signals Q2 and Q3 by masking the trigger signal Q1 by the B phase pulse signal E2. Pulse signals Q4 and Q6 having the cycle in two times of the A, B phase pulse signal are generated from the signals Q2 and Q3 by a flip-flop circuit FF, and the shift quantity signal INT and the direction judging signal DIR are outputted into a motor control circuit MDRC on the basis of both the pulse signals.
