Line 1:

In [[control theory]], a '''proper transfer function''' is a [[transfer function]] in which the [[Degree of a polynomial|degree]] of the numerator does not exceed the degree of the denominator. A '''strictly proper''' [[transfer 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.
