why do we need time domain & frequency domain.Differentiate between them...

Answer / allanki sanyasi rao

In the time domain, voltage or current is expressed as a function of time.
Signals can also be represented by a magnitude and phase as a function of frequency.
Frequency domain representations are particularly useful when analyzing linear systems.
when we want to know frequency components of a signal we go for frequency domain analysis.
