Teisendusfunktsioonid, known in English as transfer functions, are a fundamental concept in control systems engineering and signal processing. A transfer function is a mathematical representation of the relationship between the input and output of a system, assuming the system is linear and time-invariant. It is typically expressed in the Laplace domain or the z-domain, depending on whether the system deals with continuous or discrete time signals, respectively.
In essence, a transfer function describes how a system transforms an input signal into an output signal.
The poles and zeros of a transfer function are critical parameters that determine its characteristics. Poles
