I am a beginner Electronics enthusiastic and I am trying to build a circuit and I kind of know how to go about assembling the circuit but I do not understand purpose of some of components in the circuit. I have attached an image of the circuit for your reference.

- The Purpose of the 6.8k, 100 nF and 680k ?
- The Purpose of the combination of 100 nF and 680k in the first op-amp and 2nd op-amp ?
-The Purpose of the combination of 1uF and 68k ?
Also note shown on this circuit what will be the Purpose of a Comparator and how does it generate square pulse if attached to the two stage op-amp at the IC2 pin 7 ?
Thank you So much.
