Taps, from the stages of a delay line (T31 to T3(m-1)) through which the digital signals are shifted, supply first address inputs of a fixed word store (ROM) which has second address inputs supplied with a clock pulse signal (C2). The word produced by the fixed word store depends on the combination of signals at the first address inputs and can be converted in a digital-to- analogue converter (D/A) to provide an analogue output signal of the filter which can be used as a base band filter. <IMAGE> |
