the others are zero. If the PLSI is chosen of the form the sufficient conditions of (9) are satisfied if a 2 8, and A(z1, z2) # 0, lzl I < 1, Iz2 I < 1. The PLSI's of lower degree are also minimum phase for those values of a. the sufficient conditions are satisfied for a 2 3. 5. 2) Let ~ (z , , z 2) = 1 + p z 2 + a z t z , 1/ 31 2 1, a > 0. Since B (0 , z… (More)

A (Z, , Z,) has no zeros as the unit hypercircle, however, for the optimal PLSI case the correctness of the modified Shanks' conjecture needs to be investigated. A classification of LSI polynomials into optimal and subopti-mal LSI polynomials is presented in this note. By an example it is shown that a suboptimal LSI polynomial can be unstable even if the… (More)
