1. A method, comprising:
receiving a signal comprising a telemetry portion and a noise portion;
identifying one or more harmonic frequencies in the signal that are part of the noise portion of the signal;
determining whether the one or more harmonic frequencies are in a predetermined frequency band;
determining whether a signal-to-noise ratio (SNR) of the signal is below a predetermined SNR threshold; and
generating one or more notifications in response to:
the determination whether the one or more harmonic frequencies are in the predetermined frequency band; and
the determination whether the SNR is below the predetermined SNR threshold.
