Abstract
A now method for evaluating the power spectral density of multitrack c onstrained sequences is demonstrated for multitrack (OI G/I) constrain ts. (0, G/I) constrained sequences are used in magnetic recording syst ems that employ partial response maximum likelihood (PRML) signalling. Using the proposed approach the number of states in a directed graph representing the given (0, G/I) constraint is reduced remarkably sc th at the power spectral density can be easily calculated.
