Use MATLAB to:

Question 1:

1.1 Generate and plot using 'stem' the signal a = [1, 7, 3, 4, 5, 1, 2, 0]. Your signal should start from sample 0.

1.2 What is the number of samples of this signal? (show your code)

Question 2:

2.1 Generate and plot using dots the signal b= sin(2x) + 1 where x is from 0 to 2pi, using 50 samples.

2.2 What is the minimum of the signal? (show your code)
