We must also change the all pass filters on the top woofer and horn from first order to second order Butterworth. Once we use an all pass filter greater than first order we must be sure to match its alignment, or Q, to that of the low pass filter so the phase response of the low ...
When specifying a high-quality filter the αmax value should be small, the αmin value should be large, and the transition band should be as narrow as possible—that is, approximating as much as possible the frequency response of an ideal low-pass filter. The cost of this is a large ord...
Selection of the appropriate function f(.). ■ The factorization needed to get H(s) from the magnitude-squared function. As an example of the above steps, consider the Butterworth low-pass analog filter. The Butterworth magnitude-squared response of order N is (6.30)|HN(jΩ)|2=11+ΩΩhp...
