Abstract
A digital optimal filter having an especially sinusoidal pulse response uses a filter structure with a recursive and a transversal portion. The transversal portion comprises filter coefficients for the representation of scan results of half a period of the sinusoidal pulse response signal. The recursive filter structure is used to change the sign after generation of the scan results for half a period and to mark the start and the end of the pulse response. A plurality of periods can lie in between the start and the end of the pulse response, this is why the digital optimal filter can be used to extract especially sinusoidal burst signals from an original signal, namely in digital technology, which is advantageous for the implementation of IC's.
