-    The discrete convolution of two signals A and B is defined as:
-
-          A.length
-    C[i] = Σ (A[k]*B[i-k])
-          k=0
-
-    It's obvious that:  0 <= k <= A.length , 0 <= i <= A.length + B.length - 2  and  0 <= i-k <=
-    B.length - 1 From the last inequality we get that:  i - B.length + 1 <= k <= i and thus we get
-    the conditions below.
