Modulation Domain is a plane domain which is consisted of frequency and time of signals and shows the relation between frequency and time. It is a necessary field to measure signals in three-dimension space of signal (time domain, frequency domain and modulation domain).Modulation domain analysis offers a unique method for viewing complex modulated signals .Modulation Domain Analyzer (MDA) become an ideal and powerful instrument .It can be used in a wide range of applications including digital communication...
