Abstract:
1. A method for providing a digital parallelized integrator filter, the method comprising the steps of: providing a first input digital sample signal to a first adding unit; providing a second input digital sample signal, adjacent in time to said first input digital sample signal; if said second input digital sample signal follows in time the first input digital sample signal, delaying the second input digital sample signal and adding the delayed second input digital sample signal to said first input digital sample signal to provide an added signal using an adding unit; if said second input digital sample signal precedes in time the first input digital sample signal, adding the second input digital sample signal to said first input digital sample signal to provide an added signal using an adding unit; integrating said added signal using an integration unit to provide a first output digital sample signal; if said second input digital sample signal follows in time the first input digital sample signal, adding the delayed second input digital sample signal to the first output digital sample signal to provide a second output digital sample signal; if said second input digital sample signal precedes in time the first input digital sample signal, adding the second input digital sample signal to the first output digital sample signal to provide a second output digital sample signal; if said second input digital sample signal precedes in time the first input digital sample signal, delaying the second output digital sample signal to provide the second output digital sample signal; wherein the first output digital sample signal is one of an integrated signal of previous digital sample signals following in time the second output digital sample signal, if the first input digital sample signal follows in time the second input digital sample signal and an integrated signal of previous digital sample signals preceding in time the second output digital sample signal, if the first input digital sample signal precedes in time the second input digital sample signal.
