研究目的
Investigating the statistical characteristics of electromagnetic noise radiated from tube-type LED lamps and its effect on wireless medical telemetry systems.
研究成果
The study found that the band-limited time domain envelope of electromagnetic noise from several tube-type LED lamps disagreed with the APD of Gaussian noise, indicating a stronger repetitive electromagnetic noise that may degrade digital communication systems. The required carrier-to-noise ratios (CNRs) for these lamps were worse than for Gaussian noise, suggesting a need for further investigation into the error correction capabilities of wireless medical telemetry systems under such interference.
研究不足
The study did not cover all types of LED lamps, focusing only on tube-type LED lamps. The impact of electromagnetic noise on wireless medical telemetry systems was evaluated based on visual examination of ECG waveforms, which may not capture all potential effects.
