Patent ID: 8346835

Claim:
A filter structure comprising: an input, where an input signal with a symbol rate is present, several parallel branches connected to the input, with at least two analog clocked delay elements arranged consecutively with N being an even number, several parallel signal addition units connected to outputs of the delay elements each with several weighted inputs, whereby the number of signal addition units is equal to the number of parallel branches, and a control network that guides a multiphase clock signal with several individual clock signals, whereby the individual clock signals exhibit the same shape, are offset from each other by a sampling period duration and where the number of the individual clock signals of the multiphase clock signal equals the number of the parallel branches, and for controlling the delay elements with the multiphase clock signal, characterized in that in each of the branches the same number of delay elements is arranged consecutively, clock signals, which are provided for controlling delay elements that correspond to each other with regard to their position in the branches, are offset from each other by one sampling period duration, clock signals, which are provided for controlling the signal addition units, each offset from each other by one sampling period duration, clock signals, which are provided for controlling consecutive delay elements of a branch, each offset from each other by one half clock period duration, and the signal addition units connected with the outputs of the delay elements in the branches, such that all signal paths between input of the filter structure and the respective inputs of the signal addition units weighted with the same weighting factor each are guided in various branches via the same number of delay elements and via corresponding delay elements with regard to their position.
