Help needed with circuit
(OP)
Hi,
I need some help regarding a circuit operation. I will try to describe it as best I can.
Input is a 1:1 pulse train of 200-10Khz. This is fed into one input of a NOR gate. Output goes through a 10nF cap to a pullup resistor of 10K. This also goes through a 10K resistor to another NOR (other inout is tied to gnd). Output is fed back to first NOR gate. I dont understand the purpose of the feedback. Any help would be greatly appreciated.

so basically it generates a 100us pulse at 200-10Khz depending on input frequency?
