Signal communication apparatus and related receiver

摘要

There is described a receiver (4) of a signal communication apparatus; the apparatus comprises a transmitter (1) adapted to transmit coded signals, the receiver (4) for receiving the signal and a wireless interface (3) interposed between the transmitter and the receiver and comprising a transmitting antenna (L1) and a receiving antenna (L2). The receiver comprises decoding means (12) of the received signal and first means (9, 10) coupled to the receiving antenna (L2) and capable of triggering said decoding means of the received signal if the value of the received signal is outside a logical hysteresis consisting of a first logic threshold (TH_LO) having a value smaller than the value of the direct current component of the received signal and a second logic threshold (TH_HI) having a value greater than the value of the direct current component (Irde) of the received signal.
