A near field RF communicator |
摘要 |
A near field RF communicator has an inductive coupler (102) to couple inductively to an H field of an RF signal from another near field RF communicator in near field range to provide a received signal, a demodulator (300) coupled to extract any modulation from a source signal representing a received RF signal to provide an extracted modulation signal; and a controller (107) coupled to receive an extracted modulation signal from the demodulator. The demodulator (300) has a sampler (400) to sample the source signal in sampling periods and to compare signal samples with at least one of other signal samples and a clock or reference signal to remove or reject the carrier of the received RF signal and to extract the modulation. |
