سؤال 407

What is the definition of duty cycle during the averaging time for RF exposure?

  1. The difference between the lowest and highest power output of a transmitter
  2. The difference between the PEP and the average power output of a transmitter
  3. The percentage of time that a transmitter is transmittingپاسخ درست
  4. The percentage of time that a transmitter is not transmitting

توضیح

Duty cycle here means the proportion of the averaging period during which the transmitter is actually putting out RF, expressed as a percentage. It is a measure of on-air time, not a comparison between peak and average power levels.
