Abstract :
A simple interpolation formula is given to compute the pole locations of an all-pole filter whose phase is linear in the Chebyshev sense. The interpolation formula gives good results for filters with 2-10 poles and peak phase errors between 0° and 1°. Fair accuracy is achieved for peak phase errors up to 5°.
