Methods and apparatus are set forth herein. Methods and apparatus can include for example: receiving for input into an non-linear device a radio signal, the radio signal being a composite signal composed of a signal of interest and an interfering signal, wherein the signal of interest and the interfering signal are at a common frequency; controlling a power level of the radio frequency input signal received at the non-linear device so that the non-linear device provides a non-linear effect; and processing an output signal output by the non-linear device to determine a characteristic of the signal of interest.

A system of a transmitter device for the transmission of an analog signal and/or digital data provided to the system at a transmitter interface of the transmitter device is disclosed. The transmitter interface includes at least two parallel information lines. The system includes a receiver device with a receiver interface to receive the analog signal and/or digital data. The receiver interface includes the same number of parallel information lines. A transmitter protocol unit processes the analog signal and/or digital data to generate a serial data stream that includes reconstruction information. Transmission is performed via an electromagnetic field. The receiver device includes a receiver protocol unit to process and reconstruct the received serial data stream. The transmitter device is powered by electrical power provided at two power lines of the transmitter interface. The receiver device is adapted to provide power received from the transmitter device using a power recovery unit.

A source-synchronous clocking signal is sampled by an edge sampler triggered by a phase-adjusted version of the clocking signal. The output of the edge sampler is used as a phase-error indicator for a filtered feedback loop that aligns the phase-adjusted clocking signal to minimize, on average, the difference between the received source-synchronous clocking signal and the phase-adjusted version of the clocking signal minus the setup time of the sampler. This forms a delay-locked loop configuration. The phase adjustment information used to produce the aligned phase-adjusted clocking signal is then to produce a receiver clocking signal that is used to sample the source-synchronous data signal.

A method and a circuit are arranged for adapting a first reference value for generating a first bit stream from an input signal by a first amplitude adapting unit. The input signal comprises a first and a second signal. The first signal and the second signal form a baseband sum signal. A first non-linear component demodulates the input signal and outputs a demodulated input signal. The amplitude adapting unit outputs the first bit stream from the demodulated input signal on the basis of a first reference value. A reference-value adapting unit comprises a detection unit which detects the first and the second signal. Upon discontinuation of the first and second signals, an adjusting unit adjusts the first reference value to a basic reference value.
