ABSTRACT
Thus, mathematical representation of such disturbances can be used to predict the effects on the output.
If the transfer function is represented as a ›rst-order transfer function, then
G s Y s X s s
( ) ( ) ( )
= =
+
1 1τ
. (3.1)
Such a ›rst-order system has a “unity gain” as the value of the numerator in Equation 3.1. Also, the ratio of output to input in the Laplace transformations is the transfer function.
