<p>An electronic appliance comprises a signal-emitting circuit part (1) and a signal-processing circuit part (4), at least one external line for supplying the signal processing part (4) with operating current and/or at least one signal line (6) and/or at least one signal output line, at least one filter network (7) incorporated in the signal line (6) upstream of the signal-processing circuit part (4) comprises additional attenuation members for the signal line (6) and/or the operating current line and/or the output line in order to attenuate the parasitic voltages induced in the cable system by external high-frequency fields. The amplitude of said attenuation elements is greater, preferably considerably greater than the linear control range of the circuit element of the signal-processing circuit part (4). The attenuation elements and filternetworks are preferably monolithically incorporated in the signal-processing circuit part (4). The teaching of the invention can also be applied to the signal-emitting circuit part (1) in so far as the induced parasitic voltages affect its signal output.</p> |
