signal processing...........

hi.. can anyone tell what is time domain and frequency domain and their usages applications please..

@ signal
time domain and frequency domain both are used for analyzing a signal
in time domain it is difficult to analyze a frequency components as signal has frequency and phase
so we convert form time to frequency and at the end even we need results in time domain as it is easy to understand in our daily life so we convert into time domain but it is easy to analyze signal in frequency domain

As far as I know, it tells the present date and time of a certain location.
