[brmarcum] takes us back to analog building block basics with his Frequency Modulation and Demodulation tutorial. Frequency Modulation (FM) sounds simple at first, but understanding the ...

To achieve this it is normally necessary to allow a bandwidth equal to twice the maximum frequency of deviation plus the maximum modulation frequency. In other words, for a VHF FM broadcast station ...

Part 1 explains the basics of amplitude modulation (AM) and frequency modulation (FM), as well as their relative strengths and weaknesses. Part 3 discusses Direct Sequence Spread Spectrum ... Figure 3 ...

In AM, the amplitude of the signal is varied to encode the data. Frequency modulation (FM) is another type of digital modulation. ... A constellation diagram in Figure 3b shows the same information.

FM Modulation Methods. Frequency modulation has been around for over 80 years thanks to inventor and EE Edwin Armstrong. ... Figure 3 shows a simplified diagram with the main system blocks.
