Device and Method for Decoding Magnetic Patterns |
| 摘要 |
A device for decoding magnetic patterns printed on documents comprising a reading head (12) having: a reader (20) arranged to read first magnetic signals belonging to the magnetic patterns and to electromagnetic noise due to sources internal and/or external to the device. The device further comprises: a further reader (40), arranged to read second magnetic signals belonging to the electromagnetic noise, an adder component (25) arranged to algebraically subtract the amplified second magnetic signals from the amplified first magnetic signals, and a converter (16) arranged to convert the resulting signal into a digital signal representing the read magnetic patterns. A method for decoding magnetic patterns is also disclosed. |

1. A device for decoding magnetic patterns printed on documents, comprising
a reading head (12) having a first reader (20, 112) arranged to read first magnetic signals, said first magnetic signals being related to the magnetic patterns and to electromagnetic noise due to sources internal and/or external to the device; characterized by a further reader (40, 140) arranged to read second magnetic signals related to the electromagnetic noise; an adder component (25, 125) arranged to algebraically subtract said second magnetic signals from said first magnetic signals; and a converter (16) arranged to convert the resulting signal into a digital signal representing the read magnetic patterns. |
