Transfer function#

The Transfer function block implements a mathematical model of the general view transfer function (1):

(1)#\[ W(s)=\frac{b_{0}+b_{1}\cdot s+b_{2}\cdot s^{2}+...+b_{m}\cdot s^{m}}{a_{0}+a_{1}\cdot s+a_{2}\cdot s^{2}+...+a_{n}\cdot s^{n}} \]

The numerator and denominator coefficients are set as arrays in block properties \([b_{0}, b_{1}, ... , b_{m}]\) и \([a_{0}, a_{1}, ... , a_{n}]\), respectively.

3. Code generation#

Important

Block supports C source code generation

Hint

The block supports displaying values of coefficients on blocks instead of an image of the block itself
