Consider the following two discrete time signals:

a) Calculate the discrete time convolution of the two signals using MATLABs conv function and plot the result.

b) Calculate the discrete time convolution of the two signals WITHOUT using the conv function. HINT: You have to use the iterative calculation method. To do this, first estimate the range of result (n) and then at every value of n compute y[n] using the convolution sum formula. Plot the result.
