inverselaplace (3se^{-s})/(2s^2+8)

Lösung

inverse laplace transformation

\frac{3 s e ^{- s}}{2 s ^{2} + 8}

Lösung

H (t - 1) \frac{3}{2} cos (2 (t - 1))

Schritte zur Lösung

L^{- 1} {\frac{3 e ^{- s} s}{2 s ^{2} + 8}}

Wende inverse Transformationsregel an: if

L^{- 1} {F (s)} = f (t)

dann

L^{- 1} {e^{- a s} F (s)} = H (t - a) f (t - a)

Wo

H (t)

Heaviside (Schritt) Funktion ist

= H (t - 1) L^{- 1} {\frac{3 s}{2 s ^{2} + 8}} (t - 1)

L^{- 1} {\frac{3 s}{2 s ^{2} + 8}} : \frac{3}{2} cos (2 t)

= H (t - 1) \frac{3}{2} cos (2 (t - 1))
