(a) Using the KHN biquad with the output summing amplifier of Fig. 17.24(b), show that an all-pass function is realized by selecting RL = RH = RB/Q. Also show that the flat gain obtained is KRF /RH . (b) Design the all-pass circuit to obtain 0 = 105 rad/s, Q = 4, and flat gain = 10. Select appropriate component values.
