ABSTRACT:
A digital comb filter contains filter stages. Each filter stage has a latch disposed at a filter stage input, which latch, by outputting each input data value twice in each case doubles the sampling rate. Each filter stage further has a filter structure, a partial transfer function {overscore (H)} (z) of which is {overscore (H)}(z)α(1+z−1)k−1, where k is an order of the filter device and z−1is the z transform of a delay by one sampling pulse. The implementation according to the invention does not require an error correction circuit.
