ADAPTIVE AMPLITUDE EQUALIZATION

A technique is described for performing adaptive equalization on magnetic recording signals for (d, k) run-length codes, where d / 0.

It is assumed that for the given run-length code d / 0, the read pulse is symmetrical, the pulse width is less than 4 data bits, and the signal has passed through an automatic gain control circuit. Such a signal is illustrated in the figure.
