Transfer Function

Single Input Single Output continuous control block  Description The Transfer Function component multiplies the complex input by a transfer function consisting of a rational polynomial in $s$ specified by the real vector parameters $a$ and $b$ and evaluated at $s=jw$, where $w$ is a real input. Equations $y=\frac{\sum _{k=1}^{{n}_{b}}{b}_{k}{\left(jw\right)}^{{n}_{b}-1}}{\sum _{k=1}^{{n}_{a}}{a}_{k}{\left(jw\right)}^{{n}_{a}-1}}\left\{\begin{array}{cc}\stackrel{&conjugate0;}{u}& \mathrm{Use Conjugate Input}\\ u& \mathrm{otherwise}\end{array}$ ${n}_{a}=\mathrm{dimension}\left(a\right)$ ${n}_{b}=\mathrm{dimension}\left(b\right)$ Connections
