We have been given this circuit to determine the purpose of it, but I have no idea what it does. I heard someone say they are for spotlights in a nightclub for example. I have worked out some graphs in which is oscillates, and found the period of the P- but was stuck from here.

I have attached the circuit on this post for a clearer view. From my guess is that is used for a clock but might be wrong and thinking of something completely different?? Because it has an A-Stable and a COUNTER, it resets from point R.

Could someone please tell me how 1) this circuit could be used for spotlights or a clock? and 2) how to actually determine what it is used for?

Thank You Danny
