1. Given u[n] the unit step sequence, using the stem function plot the following :-

• u[n - 3] - u[n - 8]

• u[8 - n] - u[4 - n]

• u[6 - n]

f1 = @(x) sin(3*x)

f1 = function_handle with value:

@(x)sin(3*x)

f2 = @(x) sin(8*x)

f2 = function_handle with value:

@(x)sin(8*x)

f3 = @(x) f1(x) - f2(x)

f3 = function_handle with value:

@(x)f1(x)-f2(x)

fplot(f3, [-10 10])
