The invention relates to a method of implementing programmable tuned filters, in particular for telegraph signal receivers, and also to tuned filters obtained by the method. A resonator (16) organized around a multipath filter and controlled by a first clock signal is associated with a comb filter (17) organized around a delay line (21) and controlled by a second clock signal, in order to constitute a tuned filter which is programmed by the clock signals. The invention is applicable to making programmable tuned filters and banks of such filters, in particular for remote protection equipment in grids for transporting electrical power.
