  "textContent": "System, methods, and other embodiments described herein relate to sampling signals to derive information from a target frequency outside a detectable range by exploiting physical phenomena. In one embodiment, a method includes sampling, by a detector with an oscillator, a signal at sampling times to acquire a target frequency, the sampling times having an offset associated with random jitter and the target frequency is outside a detectable range for the sampling times. The method also includes computing a sample average associated with the sampling times for component frequencies of the signal using a discrete Fourier transform (DFT). The method also includes, in response to the sample average satisfying a threshold for the target frequency, extracting information by the detector for the target frequency at one of the component frequencies. The method also includes modifying control of a device using the information.",
