<p>The method involves producing received signals (S111, S112) from a carrier signal (S20) using two signal transformation units, where one of the received signals is inverse to the other received signal. The received signals are shifted to each other approximately around 180 degree phases, and are scanned at peak values i.e. positive peak values, so that stage signals (S121, S122) are produced. A demodulated output signal (S130) is produced from the stage signals, and the signal transformation units are connected parallel to each other. An independent claim is also included for a circuit arrangement for demodulation of signals wirelessly transmitted over an electromagnetic field.</p> |
