Abstract: A system may be provided and may include a first transmitter; a first antenna, coupled to the first transmitter; wherein the first transmitter is arranged to transmit via the first antenna first radio frequency (RF) signals; a first receiver; a second antenna, coupled to the first receiver; the second antenna differs from the first antenna; an RF acquisition module that is arranged to acquire second RF signals that are representative of the first RF signals; and an RF suppression module, arranged to receive the second RF signals and to generate RF suppression signals for suppressing an effect of a transmission of the first RF signals on the first receiver, and to provide the RF suppression signals to the first receiver.

Abstract: A filter includes an input and an output. First and second filter stages having respective stage inputs and stage outputs are connected in cascade between the input and the output. Each filter stage includes an amplifier having an amplifier input and an amplifier output and an inner feedback loop connecting the amplifier output to the amplifier input. An outer feedback loop connects the stage output of the second filter stage with the stage input of the first filter stage. The first and second filter stages and the outer feedback loop are arranged so that an s-space closed-loop transfer function of the filter includes two zeros and a single pole.
