Fonction triangle fourier
WebUn signal triangulaire ou signal triangle est une sorte d'onde non sinusoïdale que l'on rencontre le plus souvent en électronique ou dans le cas du traitement du signal. Il est périodique, linéaire par morceaux et continu. Tout comme le signal carré, il ne contient que des harmoniques impairs. WebDec 8, 2024 · Therefore, the Fourier transform of the triangular pulse is, F[Δ(t τ)] = X(ω) = τ 2 ⋅ sinc2(ωτ 4) Or, it can also be represented as, Δ(t τ) FT ↔ [τ 2 ⋅ sinc2(ωτ 4)] The graphical representation of magnitude spectrum of a triangular pulse is shown in Figure-2.
