perform the convolution by using matlab

Given:

1. 𝒙(𝒏) = [𝟏 𝟐 𝟑 𝟓 𝟕 𝟗 𝟒] 𝒂𝒏𝒅 𝒉(𝒏) = [−𝟏 𝟐 − 𝟑]

2. 𝒙(𝒏) = [𝟏 𝟒 𝟔 𝟕 𝟖 𝟑 𝟓 𝟐] 𝒂𝒏𝒅 𝒉(𝒏) = [𝟏 𝟏 𝟏 𝟏]

you are required to:

• Performing the convolution to find a y(n). Then, proved the h(n) value by performing the deconvolution by using MATLAB software, you are required to: Show the coding for convolution function In each question, attached 3 figures for x(n), h(n) and y(n)

x=[1 2 3 5 7 9 4]

h=[-1 2 -3]

y=conv(x,h)

subplot(411),stem(x),title('x(n)')

subplot(412),stem(h),title('h(n)')

subplot(413),stem(y),title('y(n)')

h1=deconv(y,x)

subplot(414),stem(h1),title('h(n) by deconvoltion')
