compute the convolution and plot the sequence

Write a MATLAB program to compute the convolution of the following sequences

x=[1 2 3 4 5 6], y=[1, 1 ,1]

(a) Plot the signal x and y using stem plots as two subplots in a single figure window

(b) Plot the convolved sequence in a separate figure window

Answer 1

[Chunru]

x=[1 2 3 4 5 6]; 
y=[1, 1 ,1]  

y = 1×3

1 1 1

z = conv(x, y);
stem(z)
