1. A welding system, comprising:
- a welding power supply configured to provide welding power for a welding application through a weld cable; and
a processor disposed within the welding power supply, wherein the processor is configured to transmit and receive data related to a welding operating parameter through the weld cable, to transmit one or more modulated or unmodulated tones through the weld cable, to determine an equalization filter coefficient related to the weld cable based on the one or more modulated or unmodulated tones, and to use the equalization filter coefficient to compensate for a distortive characteristic of the weld cable.

11. A method, comprising:
-
transmitting an initial modulated tone and an initial reference tone through a weld cable from a transmitter; receiving a modulated tone and a reference tone through the weld cable at a receiver; applying a digital filter function to the reference tone to determine one or more differences between a template for the initial reference tone and the reference tone; determining one or more channel equalization filter coefficients based on the differences between the template for the initial reference tone and the reference tone; and compensating for a distortive characteristic of the weld cable based on the one or more channel equalization filter coefficients. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A welding system, comprising:
-
a welding wire feeder configured to output welding wire for a welding application; and a processor disposed within the welding wire feeder, wherein the processor is configured to transmit and receive data related to a welding operating parameter through a weld cable, to transmit one or more modulated or unmodulated tones through the weld cable, to determine an equalization filter coefficient related to the weld cable based on the one or more modulated or unmodulated tones, and to use the equalization filter coefficient to compensate for a distortive characteristic of the weld cable. - View Dependent Claims (19, 20, 21, 22, 23, 24)
