abstract: |
Linear digital signal processing consists in convoluting the input sampled signal with the discrete
version of the impulse response of a filter designed
by an expert. More than often, a unique impulse response does not represent the complete knowledge
of the expert who should have proposed more than
one appropriate filter. In a recent paper, we have
proposed an extension of the finite impulse response
filtering that able to represent the fact that the filter is imprecisely known. This extension leads to
compute an interval-valued filtered signal. In this
paper, we propose a natural follow-up of this work
by considering interval-valued input signals and replacing the Choquet integral by the Sipos integral. |
