Analysis of Dynamic Systems

Schedule:

The complex variable $s$ has two components:

So, $s = \sigma + j \omega$.

$G(s)$ is a function of the complex variable $s$, when for each value of $s$ there exists a corresponding value (or several) of $G(s)$.

$$G(S)=Re (G) + J Im (G)$$

For example:

$$G(s)=\frac{1}{s(s+1)}$$
