Define the term "harmonics" in radio transmission.

The term "harmonics" in radio transmission refers to frequencies that are integer multiples of a fundamental frequency. Essentially, if you have a fundamental frequency, the first harmonic would be twice that frequency, the second harmonic three times, and so forth. This concept is critical in radio transmission as harmonics can affect how signals are transmitted and can influence the design of antennas and tuned circuits. Understanding harmonics is key for audio processing and ensures efficient signal transmission while minimizing interference.

In radio systems, these harmonics can also be crucial for analyzing and ensuring signal integrity, as they can sometimes lead to unwanted effects if they are not properly accounted for. This understanding of harmonics helps radio operators optimize their systems to achieve clearer communication.
