Abstract: A circuit for controlling frequency and/or phase response characteristic of a signal amplification system or channel has a serial architecture composed of a plurality of cells and a selector for deriving the signal after any one of the cascaded cells. At least a component of the RC network of each cell is in the form of a plurality of modules of fractionary value connected in series. A short-circuiting switch is associated with each module of fractionary value and the overall effect may be selected by selecting the derivation node of the output signal and a certain configuration of the short-circuiting switches of the RC networks of the various cells. An outstanding flexibility of selection is achieved.
