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 one component of the RC network of each cell is in the form of a plurality of elements connected in series, each of the elements having a value which is a fraction of the design value of the component. A short-circuiting switch is associated with each element; the overall effect may be chosen 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.
