ANALOG-DIGITAL CONVERSION METHOD WITH LOGARITAL TRANSFER CHARACTERISTIC AND CALIBRATION FOR BIPOLAR DIFFERENTIAL SIGNALS

摘要

THIS INVENTION DEVELOPED IN THE AREA OF ELECTRIC TECHNICAL ENGINEERING, CONCERNS A METHOD FOR PROCESSING AND CONVERSING DIFFERENTIAL ANALOG SIGNS IN DIGITAL CODES USING A CARIBRATIC CHARACTERISTIC LAW. DIGITAL ANALOG CONVERSION IS PERFORMED BY DIFFERENTIAL VOLTAGE CONVERTERS WITH LOGARITIC TRANSFER CHARACTERISTICS, ADJUSTABLE DELAY AND LINEAR TRANSFER CONVERTERS. A MINIMUM OF A CONVERSION BLOCK DIFFERENTIAL VOLTAGE, ADJUSTABLE DELAY BLOCK AND A TIME-DIGITAL CONVERSION BLOCK ARE NEEDED TO PERFORM THE PROCESSING AND CONVERSION OF THE ANALOG SIGNAL OF INTEREST. THE USE OF A DIFFERENTIAL-TIME VOLTAGE CONVERTER AND ADJUSTABLE DELAY ALLOWS TO NORMALIZE THE ANALOG SIGN OF INTEREST TO A REFERENCE VOLTAGE OF WHICH POLARITY AND WIDTH ARE KNOWN. ALONG WITH ADJUSTING THE TRANSFER CHARACTERISTIC OF THE DIFFERENTIAL VOLTAGE CONVERSION BLOCK, IT ALSO ALLOWS CALIBRATION OF THE GLOBAL CONVERSION WHICH IS MINIMIZED THE DIFFERENTIAL DIFFERENTIAL CONVERSION INFLUENCE -TIME.
