In general, a function f(t) defined on \mathbb{R} is periodic if we can find a value T such that f(t) = f(t + nT) for every t \in \mathbb{R} and n \in \mathbb{Z}. In this case we call T the period of the function or signal. We often choose the value T to be positive. The smallest n...

Web3. Does someone know how to do the Fourier Transform of the signal. x ( t) = t ⋅ sin 2 ( t) ( π t) 2. My first thought was: x ( t) = t π 2 ⋅ sin 2 ( t) t 2 = t π 2 ⋅ sinc 2 ( t) and try it with the convolution: X ( j ω) = 1 2 π ⋅ F ( t π 2) ∗ F ( sinc 2 ( t)) But the Fourier Transform of t doesn't exist I think. How can I go ... WebTo find the period T, we need to find the smallest positive value of p such that f(t+p) = f(t) for all t. Using the trigonometric identities, we can rewrite f(t+p) as: f(t+p) = 2[cos(πt+πp) + cos(2πt+4πp)] - 2 = 2[cos(πt)cos(πp) - sin(πt)sin(πp) + cos(2πt)cos(4πp) - sin(2πt)sin(4πp)] - 2
