need help: just an interpretation of this circuit

[blue6x]

HEY, GOOD DAY TO EVERYONE, I HAVE AN ATTACHED PIC OF A CIRCUIT WHICH I WOULD LIKE TO EXPLAIN IN DETAIL, BUT I CANNOT INTERPRET THIS WHOLE THING. I WOULD LIKE TO KNOW WHAT THIS OP AMPS ARE DOING..

I HAVE THIS OP AMP CONFIGURATION WHICH TELLS ABOUT INTEGRATOR AND DIFFERENTIATOR, BUT WHAT HAPPENS TO THIS CIRCUIT IS A POSSIBLE COMBINATION OF BOTH. I NEED TO KNOW IF THIS COULD BE POSSIBLE AND WHAT ARE THE POSSIBLE OUTPUT BETWEEN THOSE TWO OP-AMPS, AND THE ROLE OF THOSE CAPACITORS. NEED THIS BADLY, SO PLEASE REPLY ASAP. THANKS...

Looks like the first one is a differentiator.

The integrator would look like this:

R4-C3 form a lowpass filter. I don't know what the second OpAmp is (positive feedback?), but it's 12AM and I'm tired :|
