Optimization of the parameters of a pre-equalization low pass filter for a read channel |
摘要 |
A method is provided for defining programmed values of the boost and cut-off frequency parameters of a low pass filter of pre-equalization, of a read channel for a magnetic medium mass memory device, to ensure optimal functioning conditions of the adaptive filter of final equalization. The method includes pre-programming instantaneous digital values of the boost and cut-off frequency parameters of the low pass filter of pre-equalization for each magnetic medium, as a function of purposely sensed instantaneous operating parameters of the adaptive filter that carries out the definitive equalization of the signal during a trim scanning of the magnetic medium.
