A homework question asks to draw the DC model for a given circuit.
It has various given capacitor and resistor values, and a Vcc given voltage.
What procedure or theory would I go about in acquiring a DC model?

Please note that I am not asking for solutions or anything, just a link or anything explaining how to go about solving this.
I have searched everywhere, but to no avail.
I think I may just be having a major brain fart.

As a starting point notice that R6 & R7 form a DC voltage divider sourced by the DC supply V1. The divider output is buffered by a unity gain amplifier whose output is fed to the junction of R2 & R4. So this junction of R2 & R4 is biased to the same voltage divider value set by R6 & R7.

Hope this gives you a few clues to go on with.
