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

Lösung

inverse laplace transformation

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

H (t - 1) (1 - e^{- t + 1})

Schritte zur Lösung

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

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 - 1) L^{- 1} {\frac{1}{s ^{2} + s}} (t - 1)

L^{- 1} {\frac{1}{s ^{2} + s}} : H (t) - e^{- t}

= H (t - 1) (H (t - 1) - e^{- (t - 1)})

H (t - 1) = {01 t < 1 t \geq 1

= {0 1 - e^{- t + 1} t < 1 t \geq 1

= H (t - 1) (1 - e^{- t + 1})
