[1] H = HIGH voltage level;

L = LOW voltage level;

X = don’t care;

↑ = LOW-to-HIGH transition;

↓ = HIGH-to-LOW transition;

= one HIGH level output pulse

= one LOW level output pulse

[2] If the monostable multivibrator was triggered before this condition was established, the pulse will continue as programmed.
