Abstract: The invention relates to a method and filter structure for filtering an input signal, which is applied to an input (1) of the filter structure, having a symbol rate. The input signal is guided to multiple parallel branches of the filter structure connected to the input (1), in which at least two sequence holding members (4) are each disposed. Symbol values of the input signal, which are applied to the outputs of the sequence holding members (4) at certain points are guided to multiple (N) parallel signal addition units (3) having weighted inputs. One output signal each is generated in the signal addition units (3) as the sum of the weighted symbol values that are applied to the inputs. According to the invention, space and energy saving filter structure is provided, wherein: the same amount of sequence holding members (4.1, 4.2, 4.3) is disposed in each of the parallel branches; as many signal addition units (3.1, 3.2, 3.3, 3.

Abstract: A first data path is coupled between a data input and a data output of a circuit. A second data path is coupled between the data input and the data output. The first data path includes a parallelization circuit coupled to the data input to receive a serial data signal and configured to generate a parallelized data signal from the serial data signal, a first sampling circuit coupled to the parallelization circuit and configured to sample the parallelized data signal, and a serialization circuit coupled to the first sampling circuit and configured to serialize the sampled parallelized data signal. The second data path includes a second sampling circuit coupled to the data input and configured to sample the serial data signal. A selection circuit is configured to select between the first data path and the second data path.
