If the unit sample response is absolutely I h m I m - and the input is bounded . I x k I M Under these conditions the convolution sum is well-behaved and the output is guaranteed to be bounded. The absolute summability of h n is necessary and sufficient for this bounded-input bounded-output BIBO stability.
