<p>In the process of a circuit arrangement for converting analogue read signals, which are read by a read head of a storage device on sensing a storage medium, the signals read by the read head are converted into digital signals by amplification and filtering compensation for linear distortion, amplitude control, etc. Thereafter the profile of the processed analogue read signal is sensed and compared with a stored read signal comparison pattern which corresponds to a normal read signal. In the case of agreement, which is given on the presence of a certain correlation, this part of the read signal is evaluated as a read pulse and on non-agreement as a non-pulse. <IMAGE></p> |
