Abstract:
1. A method for identifying non-linear performance of an amplifier configured to linearly amplify signaling transmitted within a network, the method comprising: determining a first energy representative of energy within the signaling at a first frequency and a first time; determining a second energy representative of energy within the signaling at the first frequency and a second time, the second time occurring either before or after the first time; identifying non-linear performance of the amplifier in the event a first difference between the first energy and the second energy is greater than a threshold; determining a third energy to represent energy within the signaling at a second frequency and the first time; determining a fourth energy to represent energy within the signaling at the second frequency and the second time; determining a second difference between the third energy and the fourth energy being greater than the threshold; and determining a non-linearity level for the amplifier to correspond with a greater one of the first difference and the second difference, the non-linearity level representing a dominant higher order harmonic contributing to the non-linear performance to be the first frequency if the first difference is greater and to be the second frequency if the second difference is greater.
