Abstract

A METHOD FOR DECODING F2F SIGNALS AS WELL AS A DEVICE FOR DECODING F2F SIGNALS READ FROM A MAGNETIC DATA CARRIER IS PROVIDED. THE SIGNAL READ FROM THE CARD BY A MAGNETIC READING HEAD 91 IS AMPLIFIED BY AN AMPLIFIER 912 WITH A VERY HIGH GAIN, DISCRIMINATED IN A DISCRIMINATION AND INTEGRATION STATION 913 TO RECEIVE A BINARY LOCKING SIGNAL. OUT OF THIS DIGITIZED SIGNAL IN A REFERENCE TIME ACQUISITION STATION 917 A START-UP TIME VALUE IS SET AND A PHASE IS ESTIMATED TO DETERMINE THE CORRECT END OF A BIT CELL IN A PHASE ESTIMATING STATION 918. IN A SYMBOL CORRECTION STATION 920 THE RECEIVED BINARY SIGNAL IS CORRELATED WITH ALL POSSIBLE SYMBOL COMBINATIONS BASED ON THE ESTIMATED PHASE TO CREATE A CORRECT BIT STREAM. THIS BIT STREAM MIGHT BE PROCESSED FURTHER BY A BIT RECOVERY STATION 922 PROVIDING A CORRECTED BIT STREAM READY FOR INTERPRETATION. (FIG. 9)
