摘要： A method and apparatus for providing a read channel having imbedded channel signal analysis is disclosed.The method and apparatus disclosed determines the types of noise present in a read signal and separates different noises out of the read signal. A signal is read from a storage medium and a written signal is removed from the read signal to produce a noise residue signal. The noise residue signal is converted to a power residue signal. The power residue signal is correlated with a Pseudo Random Bit Sequences (PRBS) sequence used to generate the written signal to produce a deconvolved signal. The deconvolved signal is accumulated.
