METHOD AND APPARATUS FOR ACTIVE LOAD IMPEDANCE MONITORING |
| 摘要 |
An apparatus that includes a power amplifier; a load that is operatively connected to be electrically driven from the power amplifier; and an impedance monitor that is configured to in real-time identify a favorable segment within an output waveform of the power amplifier, model the baseline power spectral density of a load driven by the power amplifier during the identified segment of the output waveform, sample an empirical power spectral density of the load during the identified segment of the output waveform, and indicate a load fault in the event that the empirical power spectral density deviates from the baseline power spectral density beyond at least one pre-determined error criteria. |

1. A method comprising:
identifying a favorable segment within an output waveform of a power amplifier; modeling a baseline power spectral density of a load driven by the power amplifier, during the identified segment of the output waveform; sampling an empirical power spectral density of the load during the identified segment of the output waveform; and indicating a load fault in the event that the empirical power spectral density deviates from the baseline power spectral density beyond at least one pre-determined error criteria. |
