Abstract
A filter includes cascaded building blocks, for filtering an incoming signal. Each building block has first and second delay elements. A first scaling device is between an input node of the first delay element and an output node of the second delay element, and a second scaling device is between an output node of the first delay element and an input node of the second delay element. The building block has a cross scaling device between the output nodes of the first delay element and of the second delay element, and/or between the input nodes of the first delay element and of the second delay element. The building block is configured such that, in operation, incoming signals at the input node and output node of the second delay element are summed together.
