1)Plot a sinusodial function with amplitude 10 V and frequency 200 Hz. Get time 0 to 1000 with interval 10 (t=0:10:1000). Hint: title('name and surname'); 2)Stem an decreasing exponential function with interval -10 to 10. Hint: use "linspace, use "exp function. 3) Solve the system below and stem y(n). X[n]= (1/4)*(u(n)-u(n-5)), H1[n] = 8[n] + 28[n - 2] + [n - 3] + 38[n - 4] -2 8[n-5), H2[n] = 38[n-1] + 28[n - 2] , y(n) x(n) H2 4) Write a sinc function with duty=0.5, amplitude=5, with interval n=1:0.1:50. Plot function then bar it with bar function
