Abstract
An electronic filter device for the reception of TV-signals, comprising a plurality of frequency determining elements settable by means of an analog setting voltage, a memory (2) for storing digital values representative of the analog setting voltages and conversion circuitry (11-14) for converting the digital values into the analog setting voltages. The conversion circuitry comprises a first part (11-13) for generating a digitally modulated signal for each digital value, the digitally modulated signal having a modulated characteristic representative of the digital value, and a second part (14) for converting each of the digitally modulated signals into the analog setting voltages.
