Lösung

inverse laplace transformation

\frac{5}{s ( 4 s ^{2} + 4 s + 1 )}

5 H (t) - 5 e^{- \frac{t}{2}} - \frac{5 e ^{- \frac{t}{2}} t}{2}

Schritte zur Lösung

L^{- 1} {\frac{5}{s ( 4 s ^{2} + 4 s + 1 )}}

Ermittle den Partialbruch von

\frac{5}{s ( 4 s ^{2} + 4 s + 1 )} : \frac{5}{s} - \frac{10}{2 s + 1} - \frac{10}{( 2 s + 1 ) ^{2}}

= L^{- 1} {\frac{5}{s} - \frac{10}{2 s + 1} - \frac{10}{( 2 s + 1 ) ^{2}}}
