Реферат: A filter circuit arrangement is provided for restricting the injection, into the mains supply network, of radio frequency interference resulting from noise emanating from equipment driven from the mains supply. The arrangement includes an active portion, incorporating a unity gain amplifier (13), and a passive portion (11) which conditions the noise so that the active portion can process it. All non-inductive components are preferably provided in the form of a module (Fig. 8) fabricated, for example, in printed circuit or hybrid form; the invention permitting the use of components with reduced physical size as compared with components used in conventional, passive filter circuit arrangements.
