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.
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
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.
Tone modulation through of modulating a carrier frequency using the charactoristics of a sound, its the method used for telephone
Living things can be classified using diagrams called a phylogenetic tree or a cladogram, which show the evolutionary relationships between different organisms based on their shared characteristics. These diagrams help scientists understand the evolutionary history and genetic relationships of living things.
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.
amplitude modulation using collector modulator gives:More symmetrical envelope• Higher power efficiency• Higher output power• Need higher amplitude modulatingsignal
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.
using a venn diagrams to see the ways in which two characters are similar and different
using computer diagram
PPM is a type of pulse modulation where messages are sent using single pulses. PWM is a type of modulation which conforms to the pulse. PAM is a type of modulation in which the information is encoded into a series of pulses.
