Latest Patents

Kogan holds a patent for "Histograms of processed noise samples for measuring error rate of a PRML." This invention provides a method and apparatus for measuring the error rate of magnetic recording devices, such as hard disks. The apparatus includes a partial response maximum likelihood data detecting channel (PRML channel) that features a noise processing unit. This unit is connected between the output of an A/D converter and the input of a sequence detector. The method involves estimating a sequence of noise samples, processing them with predetermined sets of coefficients, and accumulating histograms of processed noise samples. This data helps determine the dependence of errors on a criterion that characterizes the signal-to-noise ratio of the PRML channel.
