1. An electric power signal conditioning and drive-sense circuit (DSC) sensing system, the system comprising:
an electric power conditioning module operably coupled to receive an electrical power signal and to generate a conditioned electric power signal, wherein, when enabled, the electric power conditioning module configured to perform one or more adaptation operations on the electrical power signal to generate the conditioned electric power signal; and
a drive-sense circuit (DSC) operably coupled as a sensor to monitor the conditioned electric power signal, wherein, when enabled, the DSC configured to:
sense the conditioned electric power signal via a single line;
detect an effect on the conditioned electric power signal that is based on the one or more adaptation operations that is performed on the electrical power signal by the electric power conditioning module in accordance with generating the conditioned electric power signal; and
generate a digital signal representative of at least one of an electrical characteristic of the conditioned electric power signal or the one or more adaptation operations.
