MATLAB LAB2 EX2(e)

Exercise 2 (Convolution Sum) Convolution of two infinite length sequences x[n] and h[n] is given by
y[n] = x[n] ∗ h[n] = summation x[k]h[n − k] ,   (summation limit ∞ upper side & k=−∞ lower side)

e) Perform the convolution using the ‘mconv’ function for the input sequence x[n] and system impulse
response h[n]
x[n] = [3, 11, 7,~0, −1, 4, 2]
h[n] = [2,~3, 0, −5, 2, 1]

a = [3,11,7,0,-1,4,2]
ax= [-3;3]
b= [2,3,0,-5,2,1]
bx = [-1:4]
[v,z]= mconv(a,ax,b,bx)
stem(z,v)
