could some help me on this thankyou
find the new transfer fuction relating x and y for the 2 blocks
a) b = (d^2)x/(dt^2) + (4dx)/(dt) + 6x
b) y = (d^2)b/dt^2 + 8db/dt + 2b
The transfer function of a is...
$\displaystyle f_{a} (s)= \frac{1}{s^{2} + 4\cdot s + 6}$ (1)
... and the transfer function of b is...
$\displaystyle f_{b} (s)= \frac{1}{s^{2} + 8\cdot s + 2}$ (2)
The transfer function of the cascade of a and b will be...
$\displaystyle f(s)=f_{a} (s) \cdot f_{b} (s)$ (3)
Kind regards
$\displaystyle \chi$ $\displaystyle \sigma$
