In control theory, a proper transfer function is a transfer function in which the degree of the numerator does not exceed the degree of the denominator.
A strictly propertransfer function is a transfer function where the degree of the numerator is less than the degree of the denominator.
The difference between the degree of the denominator (number of poles) and degree of the numerator (number of zeros) is the relative degree of the transfer function.
Example
The following transfer function:
is proper, because
is biproper, because
but is not strictly proper, because
The following transfer function is not proper (or strictly proper)
because
The following transfer function is strictly proper
because
Implications
A proper transfer function will never grow unbounded as the frequency approaches infinity:
A strictly proper transfer function will approach zero as the frequency approaches infinity (which is true for all physical processes):
Also, the integral of the real part of a strictly proper transfer function is zero.
In engineering, a transfer function (also known as the system function or network function and, when plotted as a graph, transfer curve) is a mathematical representation for fit or to describe inputs and outputs of black box models.
Typically it is a representation in terms of spatial or temporal frequency, of the relation between the input and output of a linear time-invariant system (LTI) with zero initial conditions and zero-point equilibrium. With optical imaging devices, for example, it is the Fourier transform of the point spread function (hence a function of spatial frequency) i.e., the intensity distribution caused by a point object in the field of view. A number of sources however use "transfer function" to mean some input-output characteristic in direct physical measures (e.g., output voltage as a function of input voltage of a two-port network) rather than its transform to the s-plane.
LTI systems
Transfer functions are commonly used in the analysis of systems such as single-input single-outputfilters, typically within the fields of signal processing, communication theory, and control theory. The term is often used exclusively to refer to linear, time-invariant systems (LTI), as covered in this article. Most real systems have non-linear input/output characteristics, but many systems, when operated within nominal parameters (not "over-driven") have behavior that is close enough to linear that LTI system theory is an acceptable representation of the input/output behavior.
