Abstract

A system may include at least one resistive-inductive-capacitive sensor and a control circuit configured to maintain timing parameters for operation of the at least one resistive-inductive-capacitive sensor and vary at least one of the timing parameters to control a spectrum associated with the at least one resistive-inductive-capacitive sensor, wherein the spectrum comprises one of a sensor activity spectrum of the at least one resistive-inductive-capacitive sensor and a current usage spectrum associated with electrical current delivered to the at least one resistive-inductive-capacitive sensor from a source of electrical energy.
