Abstract:
The invention relates to a method for simplifying a sampled signal digital filter, the method including at least one step for:
in order to obtain a first intermediate filter, gathering channels including discrete nonstationary operations relating to the same signal, the first channels including the nonstationary operations relating to a first signal and the second channels including the nonstationary operations relating to a second signal,
in order to obtain a second intermediate filter, on each of the first channels and second channels, commutative stationary operations with the nonstationary operations, in order to eliminate the redundant nonstationary operations, and
building the filter corresponding to the last obtained intermediate filter.
