What can be a result of harmonics in communication systems?

In communication systems, harmonics can lead to increased signal interference. Harmonics are integer multiples of a fundamental frequency generated during the operation of various electronic devices and systems. When these harmonics are present, they can overlap with the frequencies of the desired signals, causing distortion and interference. This interference can degrade the quality of communication, making it difficult for receivers to accurately process the intended signals.

Understanding the impact of harmonics is crucial in the design and operation of communication systems, as it highlights the importance of filtering and managing frequency outputs to ensure clear and reliable communication. The other options do not relate directly to the negative effects harmonics impose on signal integrity.
