I am still new in matlab and i am trying to plot those signals 𝑥1[𝑛] = 2𝛿[𝑛 + 𝐷1] − 3𝛿[𝑛 + 𝐷2] + 3𝛿[𝑛 − 𝐷3] + 2𝛿[𝑛 − 𝐷4] 𝑥2[𝑛] = 2𝑢[𝑛 + 𝐷1] − 3𝑢[𝑛 + 𝐷2] + 3𝑢[𝑛 − 𝐷3] + 2𝑢[𝑛 − 𝐷4] 𝑥3(𝑡) = 2𝑢(𝑡 + 𝐷1) − 3𝑢(𝑡 + 𝐷2) + 3𝑢(𝑡 − 𝐷3) + 2𝑢(𝑡 − 𝐷4) where D1=1, D2,=0 D3,=6 D4=0

D = [-1 0 6 8]; % D1, D2 (negative), D3, D4(changed to 8);
x1 = [2 -3 3 2];
subplot(311); stem(D, x1); % for dirac
subplot(312); x2 = [2 -3 3 2]; x2 = cumsum(x2); stairs(D, x2); % for steps
subplot(313); x2 = [2 -3 3 2]; x2 = cumsum(x2); stairs(D, x2);

Please don't do student homework assignments for them. It does not help them, except to teach them there is always someone willing to do their work for them. That is not the purpose of Answers.
