Transfer functions (TF)are frequently used to characterize the inputoutput
relationships or systems that can be described by Linear TimeInvariant (LTI)
differential equations.
Transfer Function (TF)Transfer Function (TF)Transfer Function (TF)Transfer Function (TF). The transfer function (TF) of
a LTI differentialequation system is defined as the ratio of the Laplace
transform (LT) of the output (response function) to the Laplace transform
(LT) of the input (driving function) under the assumption that all initial
conditions are zero.
Consider the LTI system defined by the differential equation
