The circuit in Figure 14–9

(b) has a high-pass transfer function given in Eq. (14–11) and repeated below

T(s) V2(8) = V(s) R R2 C1 C28 + R R CC28

In Section 14–2, we developed equal-element and unity-gain design methods for this circuit. This problem explores an equal-time constant design method. Using R1C1 =R2C2 and μ = 2, develop a method of selecting values for C1, C2, R1, and R2. Then select values so that the filter has a cutoff frequency of 500 krad=s and a ζ of 0.25. Use MATLAB to plot the filter’s Bode diagram.

T(s) V2(8) = V(s) R R2 C1 C28 + R R CC28 (R2C+R C + RC-R2 C2)s +1
