Question

High-pass Butterworth filters have transfer functions of the form HH(s) = (+-ks^n)/(Dn(s)) where n is the order of the filter, Dn(s) denotes the nth order polynomial in Table 16.3-2, and k is the pass-band gain. Obtain the transfer function of a third-order Butterworth high-pass filter having a cutoff frequency equal to 100 rad/s and a passband gain equal to 5

Answer 1

High-pass Butterworth filters have transfer functions of the form HH(s) = (+-ks^n)/(Dn(s)) where n is the order of the filter, Dn(s) denotes the nth order polynomial in Table 16.3-2, and k is the pass-band gain.
