Can someone please help me with these questions using Matlab? Thank you so much in advance.

Plot following function in Matlab over the time. a. y(t) = 10e^-t/tau, here tau = 2.5 sec b. delta_n(t) = (1, where t = plusminus 2n sec, n belongsto (-10, 10) Plot following equation over the time. Consider sampling rate at 100 Hz. a. x(t) = sin (2 pi t) + 1/3 sin(6 pi t) + 1/5 sin (10 pi t) Implement following functions in Matlab. Use sampling rate of 10Hz. a. sinc(t) for t belongsto [-10 pi, 10 pi] The function f(t) = sin (2 pi t) is sampled at various sampling rate. Therefore, sampling continuous time is replaced by discrete instance as follows. f(t) = sin (2 pi n T_s) Use subplot to plot above function is in a single plot, and scale the plots property using command. a. T_s = 1/10, 0 lessthanorequalto n lessthanorequalto 100: axis ([0, 100, -1, 1]) b. T_s = 1/3, 0 lessthanorequalto n lessthanorequalto 30: axis ([0, 30, -1, 1]) c. T_s = 1/2, 0 lessthanorequalto n lessthanorequalto 20: axis ([0, 20, -1, 1]
