ABSTRACT:
A method for decoding pulse-width modulated signals, such that a sawtooth signal is generated. The sawtooth signal is synchronized with a signal to be decoded. By comparing the sawtooth signal with a reference, a temporal center of a time period reserved for transmission of a bit can be measured, thus reducing a demodulation of the signal to a measurement of the signal level. Furthermore, a data bus for an activation system utilizing this method is also provided.
