Processor method and apparatus of the read information, signal acquisition method of information reading apparatus, band-limited processing method, a signal processing method and timing point amplitude extraction method, and the method of processing the read signal and the signal processing unit read

摘要

The information reading were able to improve the reading accuracy when there is blurred or uneven reading surface or if it improves the measured resolution with S / N of the signal to read Save your money or hardware size, depth reading expanded The method takes in a signal containing binary information from the medium 1, are arranged one-dimensionally to have a information length given on a basic unit length of the information length of the binary information from said the accepting signal Based on the basic unit length retrieves information, the extracted, it is configured to read the specific information of the length of the binary information from the acquisition of the signal.
