$G(s) = \frac{s + 1}{(s + 1)(s + 2)}$
Terms
| Term | This example | Why |
|---|---|---|
| pole | $s = -2$ | The pole of $G(s)$ is $-2$, because \(G(s) = \frac{1}{s + 2}\) after canceling $s + 1$. |
| zero (of a transfer function) | None | $G(s) = \frac{s + 1}{(s + 1)(s + 2)}$ has no transmission zeros, because the factor $s + 1$ cancels. |
