IN time domain analysis time is the independent variable.
when a system is given an excitation input is a respose output.this response varies with the time is called time response.

time domain is respected to the time and frequency domain is respected to the frequency
Convolution in the time domain is equivalent to multiplication in the frequency domain.
Design of filtering and control systems is usually easier in the frequency domain than in the time domain.
Convolution in the time domain is equivalent to multiplication in the frequency domain.
Bode plot is for Frequency Response Analysis Root-Locus plot is for time-domain analysis
with the help of laplace transform the calculation part can be reduced in frequency domain .In time domain differential equations are used and solution is cumbersome.
freguency domain concept
the use of frequency domain will prove better results were the latency is not a problem. also u can do batch processing in frequency domain hence the overall efficiency of hardware can be effectively used.....
Frequency Analysis is much easier. Some equations can't be solved in time domain while they can be solved easily in frequency domain. When moving to frequency domain you change the differential equation into algebric equation. Also, in frequency domain it is easy to apply filters and compute their specifications. In telecommunications, using multiple frequencies enables more than one user to use the service at the same time if having different frequency, this enables less delay for the signal. Also, it would be easier, when using frequency domain- to give each user, or each standard (GSM, Satellite ...) it's own frequency range without interfering. This can't be done in time domain
to find their ESD and PSD
frequency transfer function deals with transfer in frequency domain, transfer function alone can be referring to any type of transfer in different domain e.g time domain
we use fourier transform to convert our signal form time domain to frequency domain. This tells us how much a certain frequency is involve in our signal. It also gives us many information that we cannot get from time domain. And we can easily compare signals in frequency domain.
