Abstract
In an electronic circuit, comprising electrical and electronic components and their connecting lines (3) on a printed circuit board (2), in which case a shielded housing encloses the electronic circuit, attenuating radiofrequencies, in order to prevent interference which acts on the electronic circuit and interference which is caused by the electronic circuit, in particular for use in a combination display instrument in a motor vehicle. Connecting lines (3) from the electronic circuit on the printed circuit board (2) are passed out of the shielded housing (1), connecting means (5) outside the shielded housing (1, 15) are connected to the connecting lines (3), and shielding is provided which reduce or suppress the ingress of radio-frequency interference into the shielded housing (1) and the emission of radio-frequency interference from the shielded housing (1).
