6. Given two discrete-time signals x [n] and h[n: x[n] = {(0.5)", 1n1 otherwise and (b) (c) h[n] = {} 2", -1n2 0, otherwise Let y[n] be the convolution of a[n] and h[n]. Answer the following: (a) Use MATLAB to construct [n] and h[n] and then compute y[n]. (Hint: use. ^ and conv). Write down the values of y[n] for all n. Plot yn using the command stem and attach it in your report. Try the command deconv (y,x) where x and y are the vectors for x[n] and y[n]. If x[n] and y[n] represent the input and output of a system, respectively, what is the purpose of this command?
