A closed-loop system has the characteristic equation given by: $ s^3 + k s^2 + (k+2) s + 3 = 0 $.
For the system to be stable, the value of $ k $ is:
A digital filter with impulse response $ h[n] = 2^n u[n] $ will have a transfer function with a region of convergence.
Choose the minimum number of op-amps required to implement the given expression. $ V_o = \left[ 1 + \frac{R_2}{R_1} \right] V_1 - \frac{R_2}{R_1} V_2 $
