For a proportional system, output is directly proportional to input. In effect it is an amplifier or attenuator and is a simple ratio.

Example 1
Lets consider a first order link with positive proportional feedback loop.

|
Thus, the static transfer coefficient and time constant are decreased by ().
Example 2
Lets consider a first order link with negative differential feedback loop.
|
|
Static transfer coefficient doesnt change and time constant is increased by ().
