Ett s.k. rullande-medelvärdefilter (moving average) av längden N beskrivs av ekvationen
y(n)=1N[x(n)+x(n−1)+…x(n−N+1)]
Beräkna utsignalen
y(n)...
a) När N=6 och insignalen är en impuls
δ(n)
b) När N=4 och insignalen är
x(n)=[02020202](0≤n<8)
c) När insignalen är som i b och filtret istället utgörs av tre parallellkopplade filter med impulssvaren
h0(n)=δ(n)4,
h1(n)=δ(n−1)4 samt
h2(n)=δ(n−2)4
