Why is duty cycle one of the factors used to determine safe RF radiation exposure levels?
It affects the average exposure to radiation✓Richtige Antwort
It affects the peak exposure to radiation
It takes into account the antenna feed line loss
It takes into account the thermal effects of the final amplifier
Erklärung
The exposure limits are stated as averages over a fixed time window, so what matters is how much energy is delivered across that window rather than the instantaneous peak. Duty cycle sets the fraction of that window during which the transmitter is actually radiating, so it sets the average exposure.
