Method for generating an output signal uses a phase difference between a periodic reference signal and a periodic regulating signal

摘要

A reference signal (6) is scanned within a period of a regulating signal at specific scan time points (S1-S5). By relying on all scan actions (A0-A4) for the reference signal taken within the regulating signal period, output signals (PD0-PD3) are generated so as to assume one of three conditions and are suppressed in the event of a fault. An Independent claim is also included for a device.
