摘要: A system for the remote identification of objects using near-field electromagnetic coupling between an interrogator a transponder and receiver in which reply carrier at subharmonic interrogation frequency is obtained by regulating, with minimum energy loss synchronously signal, exchange process element complementary storage element, further varying, also resultant oscillation waveform, said so that becomes modulated information bearing code, modulation rate being not constrained tuned circuit bandwidth.
