    What exactly are harmonics and how do they "appear"?

    2012年5月21日 · RF systems have to put out waveforms that do not contain harmonics outside the allowed frequency range. This is how a PWM power supply (operating frequency ~100kHz, square wave) can interfere with FM radio …

    Are there harmonics in the radio spectrum?
    There is nothing inherent about having harmonics in the radio spectrum. Most communications devices use high quality oscillators and power amplifiers, and often have a bandpass filter just before the antenna, to minimize harmonics.

    What are harmonics in RF systems?
    A given signal’s second harmonic is approximately twice the given signal’s fundamental frequency. Ideally, amplifiers are expected to have zero non-linearities in the frequency. Why are harmonics generated?

    Is frequency modulation a musical instrument?
    I would say, yes, but in a different way. Radio communications are usually frequency modulated (FM) or amplitude modulated (AM). The fundamental frequency is the "carrier" wave. Frequency modulation induces harmonics, which is this case are a lot more complex than those than a musical instrument.

    Why is radio frequency spectrum important?
    Radio frequency spectrum is a limited natural resourcecritical for a huge range of terrestrial and space services on the land, at sea and in the skies. The importance of harmonizing use of spectrum across all services is not in doubt – and nor is the increasing difficulty in reaching this shared goal as demand for spectrum grows.
