11.19 An amplifier with a low-frequency gain of 100 and poles at 104 rad/s and 106 rad/s is incorporated in a negative-feedback loop with feedback factor β. For what value of β do the poles of the closed-loop amplifier coincide? What is the corresponding Q of the resulting second-order system? For what value of β is a maximally flat response achieved? What is the low-frequency closed-loop gain in the maximally flat case? 0.245; 0.5; 0.5; 1.96 V/V
