Abstract
In this paper, some new results on minimum-bandwidth system are presented. First, we state sufficient condition for the existance of a existance of a power spectral null at the zero frequency and Nyquist frequency. Second, eye boundary functions and eyewidth are obtained for minimum-bandwidth systems of arbitrary numbers of transmitted symbol levels. Third, for linear minimum-bandwidth systems usually known as PR systems, we derived formulars for evaluating DSVs and ASVs in terms of the coefficients of the system polynomials and using formulars, we obtain DSVs and ASVs of various PR systems. Last, the relations among DSV, ASV, power spectral nulls, system polynomial nulls, and the minimum-bandwidth property are summarized.
