Abstract: A method for decoding a data stream carried by a modulated signal includes receiving the modulated signal. The modulated signal is modulated according to a protocol belonging to a group of protocols including at least three protocols. The method further includes extracting a clock signal from the received modulated signal, detecting the protocol, and decoding the data stream according to the detected protocol using the extracted clock signal.

Abstract: An integrated circuit, includes: an input configured to receive an induced signal that is modulated according to a protocol belonging to the group including protocols using ASK modulation and protocols using OOK modulation; a detection circuit configured to detect the modulation of the induced signal; a decoding circuit configured to detect the protocol; a configurable limiter configured to limit a level of the induced signal and having a first configuration adapted to protocols using ASK modulation and a second configuration adapted to protocols using OOK modulation; and a control circuit configured to set the limiter in the first configuration until a protocol is detected, and to switch the limiter from the first configuration to the second configuration in response to a protocol using OOK modulation being detected.

Abstract: Intermediate digital signals Fi(?), Gi(?), i=1, . . . I, are generated, which result from a comparison of reference potentials of the first input analogue signal at a shifted value of its observed argument and with a suitably reduced amplitude to the potential, which is inverse to said potential, of the third input analogue signal at the same shifted value of the observed argument and with the amplitude reduced in said way, the shifted argument values being uniformly distributed within the first half-period. A value U of the voltage is measured at any value of the observed argument as at that time the highest one of the voltages at terminals with said reference potentials. An actual peak amplitude A of the input analogue signals is determined as A=kI,mU where the factor kI,m is a quotient of the peak amplitude of said input analogue signals and of the mean value of the voltage waveform envelope of the reference potentials pertaining to said peak amplitude.
