Abstract
In a multiplexed filtering device the first and second input signals are respectively sampled to give a third signal and sampled and delayed to give a fourth signal. An adder whose output is connected to the control electrode of a charge transfer device of a hybrid filter, adds alternately the third signal to a sampled signal corresponding to the third signal and coming from the recursive part of the hybrid filter and the fourth signal to a sampled signal corresponding to the fourth signal and coming from the recursive part of the hybrid filter. The output signals of the non-recursive part of the hybrid filter are summed by a reading amplifier, the output of which constitutes the output of the hybrid filter; after which they are demultiplexed and delayed for the restoration of the first input signal and only demultiplexed for the restoration of the second input signal.
