Modulation Domain (MOD) is a plane domain which is consisted of frequency and time of signals. It is necessary field to measure signals in three- dimension space of signal (time domain, frequency domain and modulation domain). In recent years, Modulation domain analysis offers a unique method for viewing complex modulated signals. Modulation Domain Analyzer (MDA) may be used to analyze signal features that include of frequency, time interval and verus phase time. It has a wide range of application in digita...
