Hi there all
What is that frequency used in Spektrum Radio which is 2.4Ghz? is it PPM or PCM, and as we use 72.810 or 72.830 either PPM or PCM, what these frequencies have to do with 2.4 Ghz, can anyone explain please.
Thanks
Mody
Neither, different technology.
The frequency is 2.4 Ghz, but I am not sure of what type of modulation is being used.
In the very basic form, you have three ways to transmit data on a radio wave. My changing the amplitude or strength, by changing the frequency or what Hz it is slightly, or by Phase modualtion of changing the timing of when the wave peaks and dips. All other ways are sub forms of these three basic types of modulation.
