WebbMultiple-pass moving average filters involve passing the input signal through a moving average filter two or more times. Figure 15-3a shows the overall filter kernel resulting from one, two and four passes. Two passes are equivalent to using a triangular filter kernel (a rectangular filter kernel convolved with itself). WebbFIR, Finite impulse response, betecknar en typ av filter för digitala system. Kännetecknande för dem är att impulssvaret är noll utanför ett visst begränsat intervall. Om h(n) = 0 för n < 0 och n >= M så är utsignalen y(n): = = ()Detta kan tolkas som att utsignalen är en viktad linjärkombination av de M senaste insignalsvärdena.
