Abstract (en)

[origin: EP2134025A1] The method involves determining a condition-relevant value to determine a logical condition of a signal (S2) i.e. current signal, of a communication unit (2) e.g. subscriber identity module (SIM) card, where the condition is present during a high-state of another signal (S1) i.e. voltage signal, of another communication unit (1) i.e. mobile phone's controller. The value is present at a condition-relevant sampling time point lying directly before the beginning of a falling edge of the signal (S1) and/or a condition-relevant sampling time interval lying directly before the beginning of the edge. An independent claim is also included for a device for detecting a digital signal i.e. single wire protocol (SWP) signal, that is transmitted between two communication units over a single wire connection, comprising an evaluator.
