Interface for use in electronic closing system utilized as door closing system for access authorization to transmit data of passenger car, has filter for dimensioning raising edges, where slopes of raising and falling edges are different

摘要

The interface has a resistor-capacitor (RC) low pass filter for dimensioning raising edges (26) of pulses (25) of data of the interface, and an electronic control circuit for dimensioning falling edges (27) of the pulses. The data of the interface is coded by the pulses with the raising edges and the falling edges, where slopes of the pulses are controlled, and the slopes of the raising edges and the falling edges are different. Control commands are coded by length between two raising edges and/or falling edges of the pulses.
