Hello

Only need the answer of question 5 and 6 also with the graph.

Write MATLAB code to plot the following waveforms. Submit your code and plots in a single PDF file. 1. (8 pts) Rectangular pulses: a. rect(t) b. rect(t-T) c. rect(t/t) For T and T, choose any values that make sense. 2. (12 pts) Triangular pulses: a. A(C) b. At-T) C. At/t) For T and T, choose any values that make sense. 3. (8 pts) Impulse approximation: a. 8(t) b. 6(t-T) For T, choose any value that makes sense. 4. (12 pts) Unit steps: a. (t) b. ut-T) C. A.ut-T) For T and A, choose any values that make sense. 5. (12 pts) Signums: a. sgn(t) b. sgn(t-T) C. A.sgn(t-T) For T and A, choose any values that make sense. 6. (8 pts) Causal exponential: a. eu(t) b. A.enault -T). For T, a, and A, choose any values that make sense
