My requirement is on input side pulses will be coming. When ever there is high or low on input side for a certain amount of time a pulse should be generated on output side.
Reset is driven to low when the Input stop high-low toggling.
Basically you can relate that to a watchdog timer implementation.
I am attaching a design in which i am not getting the desired output.
I am also attaching my requirement picture.

Kindly help me.
