This site does not use diagrams.
Which of the following is a disadvantage to using graphs and diagrams?
They could mean a lot of things, but in the context of each other they probably stand for Amplitude Modulation and Frequency Modulation (two different methods for sending an audio signal using radio waves) respectively.
A: A carrier carry information by modulation either Amplitude or Frequency modulation. Therefore AM and FM RADIO M stand for modulation
Well it is something like driving a car and raising a child: completely different things.
The aim is to increase capacity of the system as the signal can be represented using different phase angles as well as amplitude. F.Mmbaga
Tone modulation through of modulating a carrier frequency using the charactoristics of a sound, its the method used for telephone
High level AM modulation is a type of modulation using class c (90 percent) amplifiers. The system uses medium power tubes or transistors and is bulky.
An advantage to using graphs and diagrams in presentations is that it is easy for your audience to see what you are describing. Graphs and diagrams help get your point across.
amplitude modulation using collector modulator gives:More symmetrical envelope• Higher power efficiency• Higher output power• Need higher amplitude modulatingsignal
