Abstract:
A method (40) for controlling signal level in a digital receiver, comprising at least the following steps:amplifying an analog signal conveying digitally encoded information to be provided by the digital receiver as the output of the digital receiver, the amplifying using a first amplifier (15) of an analog circuit (35) so as to provide an amplified analog signal, providing an output analog signal (36) derived from the amplified analog signal while controlling (42) the level of the output analog signal (36), converting (44) the output analog signal (36) to a digital signal in an A/D converter (13) of a digital control circuit (34), and deriving (46) the output of the digital receiver from the digital signal, characterized in that in controlling (42) the level of the output analog signal (36), the output analog signal is tapped to provide an input to a control element (31) provided as a component separate from the digital control circuit (36), the control element (31) for providing to the first amplifier (15) a signal derived exclusively from the peak value of the output analog signal (36).
