Problem 3
Find an equation to express $v_o$ in terms of $v_A$, $v_B$, and $v_C$
Assuming all resistors equal, find $v_{out}$ in terms of $v_A$, $v_B$, and $v_C$ at DC and when $\omega \to \infty$
Bonus: Modify the circuit such that the new transfer function is second order with $\omega_o = \frac{2\pi 1000}{sec}$ rad, and Q = 1/4
