Abstract
A method and circuitry for a receiver are disclosed. In the method a signal is received in a signal processing path of the receiver. Direct voltage that is present in the received signal is reduced by compensation means (12). The amplitude of the signal is attenuated by frequency selective attenuation means (10) during the direct voltage reduction by the compensation means (12).
