Claims
- 1. A decoding device, comprising:a signal-conditioning device for generating an intermediate signal from an analog input signal for digital processing; a data register coupled to said signal-conditioning device for storing a time section of the intermediate signal; a bit decoder coupled to said data register for converting the time section of the intermediate signal stored in said data register into an output signal having at least one bit; and a pattern recognition device coupled to said bit decoder, said pattern recognition device operating on a rule basis.
- 2. The decoding device according to claim 1, wherein said signal-conditioning device includes a synchronization device having an output for outputting a digital signal and a sampling device for sampling the digital signal, and said sampling device has an output for outputting the intermediate signal.
- 3. The decoding device according to claim 1, wherein said signal-conditioning device includes a fault detector.
- 4. The decoding device according to claim 1, wherein said signal-conditioning device has a fault corrector.
- 5. The decoding device according to claim 1, wherein said pattern recognition device has parameters to be changed.
- 6. The decoding device according to claim 5, wherein the parameters are changed by software.
- 7. A smart card, comprising:a decoding device including: a signal-conditioning device for generating an intermediate signal from an analog input signal for digital processing; a data register coupled to said signal-conditioning device for storing a time section of the intermediate signal; a bit decoder coupled to said data register for converting the time section of the intermediate signal stored in said data register into an output signal having at least one bit; and a pattern recognition device coupled to said bit decoder, said pattern recognition device operating on a rule basis.
- 8. The smart card according to claim 7, further comprising a reading device having said decoding device.
