Abstract
A method for processing a digitized analog signal read from a DVD media and provided to a digital processing system is described herein. The method includes the steps of forming a first set of data from actual data read from a location on a DVD media, the location containing a known test data sequence, forming a second set of data comprising the known data bits making up the known test data sequence. The method proceeds with the steps of comparing the first set of data to the second set of data; and determining the magnitude of no more than two variables, the two variables representing at least three coefficients in an impulse response relationship which models the digital processing system, the magnitude of the no more than two variables being determined so that the error rate between the first and said second sets of data is minimized.
