What is the effect of modulation duty cycle on RF exposure?

  1. A lower duty cycle permits greater power levels to be transmittedПравильный ответ
  2. A higher duty cycle permits greater power levels to be transmitted
  3. Low duty cycle transmitters are exempt from RF exposure evaluation requirements
  4. High duty cycle transmitters are exempt from RF exposure requirements

Объяснение

Because the limits apply to time-averaged exposure, a mode that transmits only part of the time contributes proportionally less to the average. A lower duty cycle therefore allows a higher peak power for the same time-averaged exposure figure.
