IN MATLAB 2.1) Create a ‘time_shift’ function that create an outputsequence y(n) as a delayed version of the input sequence x(n). Thefunction should accept input arguments of x, n, and n_d where n_dis the number of samples delayed. 2.2) Let x(n) = 2n + 3, where n = -10:10. a.Plot x(n). b.Plot a time delayed version of x(n) delayed by 3 samples. c. Plot the time-reversal of x(n) 2.3) Plot y(n) = 5*?(n + 4) – 2* ?(n -2); n = -10:10 2.4) Plot z(n) = u(n) – u(n-4) ; n = -10:10 where ?(n) is the unit impulse sequence and u(n) isthe unit step sequence. . . .
