Chapter 8 FM and PM Now that we understand the concept of a carrier and sidebands, let us extend that to the more complex FM, or Frequency Modulation. Today, there are very few AM-only or FM-only ra-dios made; most radios cover both AM and FM broad-cast bands. So most of us listen to both AM and FM broadcast stations. Unfortunately, this often leads us to the wrong conclusions about their... BthPM dFM ilt th i il f itiBoth PM and FM waves violate the principle of superposition.

  • Comparison between FM , AM and PM : 11/30/2012 8 Comments Amplitude modulation (AM): imposing a signal on the amplitude of a frequency - has the effect of modifying the frequency a bit as well, and is much more susceptible to environmental noise such as lightning. Works well across much of the radio spectrum. Frequency modulation (FM): imposing a signal by altering the frequency - it takes …
  • The Differences Between UHF And VHF Radio Frequencies Posted by admin on September 21, 2015 VHF (Very High Frequency) and UHF (Ultra High Frequency) come with distinct pros and cons, understanding these differences will help you identify the best …
  • When you quote a frequency for a radio station, you generally quote the frequency of the carrier. But when you superimpose a signal on the carrier by AM or FM, you produce sidebands at the sum and difference of the carrier frequency f C and modulation frequency f M.
