FIELD: digital pulse engineering. ^ SUBSTANCE: proposed device designed for shaping output pulses of desired length for each of three events, that is, signal front across first control input, signal zero level from closing button incorporating provision for chatter suppression, and detection of pulse skipping across signal pulse input has seven resistors 1 - 7, two capacitors 11, 18, button 10, first and second control inputs 12, 13, pulse input 14, AND gate 17, NOT gate 8, two NAND gates 9 - 16, NOT gate with open collector output 15, and pulse signal envelope detector 19. This pulse shaper can be used, for instance, as system reset pulse shaper of numeric control device. ^ EFFECT: enlarged functional capabilities. ^ 1 cl, 1 dwg |
