🔍 Key Concepts

• RF harmonics as unwanted multiples of a transmitter’s fundamental frequency • How spurious emissions can affect other frequencies and nearby services • Regulatory requirements on emission limits and occupied bandwidth

💭 Think About

• If a transmitter radiates strong harmonics, what might happen to receivers tuned to frequencies near those harmonics? • How is the occupied bandwidth of a station defined, and does removing harmonics change that occupied bandwidth or just clean up spurious signals? • Think about the difference between staying within your assigned channel and avoiding interference on other channels or services.

✅ Before You Answer

• Distinguish between fundamental emission bandwidth and harmonic/spurious emissions • Check what the FCC/ITU rules actually limit: is it bandwidth of the authorized emission, levels of spurious emissions, or both? • Make sure you understand whether harmonics mainly affect your own channel’s width or unwanted radiation on other frequencies.
