Question

Please answer the two questions in red The application of the direct summation method to these two sequences is shown in Figure 1. The first three panels of this figure correspond to h[n]shifted by 0, 1 and 2 and multiplied by x(0],xland2] respectively. The bottom panel is the sum of the scaled and shifted sequences. 10Mn-0 . 120R-2 -2 Figure 2: Convolution by the direct summation method Notice that in this example, you have to sum three sequences of length six (including zero padding at the beginning and/or end of each sequence) to get the output.) Q: Why do we have to pad these sequences? Q: In general, how does the number of sequences we have to sum and the length of these sequences depend on the sizes of xIn]and hn]?

Explanation / Answer

1 Answer:We need padding to reduce the length of the sequence

the number of sequences depend on the x[n]*h[n]

in the above answer question

2*2=4
