摘要:
The invention relates to a reader (104) for a contactless inductive-coupling telemetry system including at least one RLC passive sensor (102) having a resistance and a capacity or an inductance that can vary based on one or more physical parameters to be measured, the reader including an inductive antenna (105), and a means for the iterative identification of at least the resistance and the capacity or the inductance of said sensor, adapted for implementing an iterative identification method that comprises the steps of: transmitting a test signal at the input of said antenna; carrying out an estimation ^yk of the time response of the sensor to said test signal using means defining a discrete filter (112) with adjustable coefficients; adapting the coefficients of the discrete filter based on a criterion J depending on said estimation and on a discrete signal sk formed from a real signal obtained at the terminals of the antenna in response to the transmission of said test signal.
