Title
(EN) Method for Attenuating a High Frequency Emission From a Clocked System
Abstract
(EN)

The method provides the following steps: determining a temporally averaged maximum value, which the power of the high frequency emission of the clocked system must not exceed in a predefined frequency band; modulating an oscillating frequency provided by the oscillator as the excitation source with a frequency deviation so that the average power is below the maximum value in the predefined frequency band; determining a bandwidth of a wireless receiver; and modulating the oscillation frequency with a modulation frequency that is greater than the bandwidth of the wireless receiver.
