Filtering method and filter
Abstract:
The invention relates to a filtering method and a filter implementing the filtering method. In the solution, a signal is filtered by at least one real FIR filter having at least one stop frequency pair whose different frequencies are symmetrically on different sides of at least one alias frequency.
