Abstract

1505887 Bank note discrimination system LAUREL BANK MACHINE CO Ltd 15 April 1975 [16 April 1974] 15520/75 Heading G4X Bank note discriminating apparatus comprises magnetizing element means for magnetizing magnetic portions of a note with an appropriate waveform at an appropriate frequency as the note is moved relative to the magnetizing element at a predetermined speed, magnetic detecting element means for detecting the distribution of the magnetization of the magnetic portion of note as it is moved relative to said magnetic detecting element at said predetermined speed, and a frequency selective amplifier tuned to the frequency determined by the frequency of the said magnetization. The preferred wave form is sinusoidal. The signal voltage detected by the frequency selective amplifier is coupled to a waveform analyser.
