ABSTRACT:
Method and apparatus for detecting valid data peaks read from a magnetic medium. Signals representing the peaks are entered into a shift register. Logic circuitry including comparator are connected to stages of the shift register to determine the relative magnitude of a peak sampled at time N versus subsequently sampled peaks. The generated magnitude information is used to determine which of the signals represent valid data peaks and which represent noise and the like.
