Question

Solve alone in matlab graphs explain the code

system and signal
1) f(t) = μ(t^2-16)
2) f(t) d(t^2-1)
3) f(t) = u(cos(2πt))
4) f(t) = μ(t-2) - u(t-2)*e^t cos(10πt)
5) f(t) = [μ(t) - 2μ(t-r) + μ(t-2r)] sin(5π/r t)

Answer 1

6 d (t^2 - 16) (t^2 - 1) f(t)^2 = u

Explanation:

6 d t^4 f(t)^2 - 102 d t^2 f(t)^2 + 96 d f(t)^2 = u
