# Solution of State Equations

$latex \displaystyle \Rightarrow &s=2 &bg=ffffff$ The output response depends on the state variables and their initial values. Hence it is necessary to obtain the state vector $latex \displaystyle x(t) &s=2 &bg=ffffff$ which satisfies the state equation at any time $latex \displaystyle t &s=2 &bg=ffffff$. This is called the solution of state equations, which helps to obtain the output … Continue reading Solution of State Equations

# Inverse Laplace Transform

Inverse Laplace Transform using Partial Fraction Method $latex \displaystyle F(s) = \frac {N(s)}{D(s)} &s=2 &bg=ffffff$ $latex \displaystyle N(s) \rightarrow &s=2 &bg=ffffff$ Numerator Polynomial $latex \displaystyle D(s) \rightarrow &s=2 &bg=ffffff$ Denominator Polynomial $latex \displaystyle \Rightarrow &s=2 &bg=ffffff$ If degree of numerator polynomial $latex \displaystyle N(s) &s=2 &bg=ffffff$ is higher than the degree of $latex \displaystyle D(s) &s=2 &bg=ffffff$, than we should divide … Continue reading Inverse Laplace Transform
