inverselaplace (4e^{(-2s)})/((s^2-4s+3))

Lösung

inverse laplace transformation

\frac{4 e ^{(- 2 s)}}{( s ^{2} - 4 s + 3 )}

H (t - 2) (- 2 e^{t - 2} + 2 e^{3 (t - 2)})

Schritte zur Lösung

L^{- 1} {\frac{4 e ^{(- 2 s)}}{( s ^{2} - 4 s + 3 )}}

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)

H (t)

Heaviside (Schritt) Funktion ist

= H (t - 2) L^{- 1} {\frac{4}{s ^{2} - 4 s + 3}} (t - 2)

L^{- 1} {\frac{4}{s ^{2} - 4 s + 3}} : - 2 e^{t} + 2 e^{3 t}

= H (t - 2) (- 2 e^{t - 2} + 2 e^{3 (t - 2)})
