Apparatus and methods of skin effect correction

摘要

Various embodiments include apparatus and methods to provide a skin- effect correction. The skin-effect correction can be based on a pre-calculated correction coefficient library. In various embodiments, a skin-effect correction procedure can be applied that only uses a single-frequency R-signal measurement. In addition, an embodiment of a skin-effect correction procedure using a single- frequency R-signal measurement can be applied whenever the quality of the data from one of the multiple frequencies normally used in a multi- frequency method is reliable. Additional apparatus, systems, and methods are disclosed.
