Why frequency domain analysis is preferred over time domain analysis?

Frequency-domain analysis is widely used in such areas as communications, geology, remote sensing, and image processing. While time-domain analysis shows how a signal changes over time, frequency-domain analysis shows how the signal's energy is distributed over a range of frequencies.

What is the difference between time domain and frequency domain analysis?

As stated earlier, a time-domain graph displays the changes in a signal over a span of time, and frequency domain displays how much of the signal exists within a given frequency band concerning a range of frequencies.

What are the advantages of frequency domain on time domain?

In designing and optimizing motion control systems, frequency domain translation of time domain data can therefore allow much greater clarity and simplicity in the analysis of system outputs.

Which is the most commonly used method to convert time domain to frequency domain?

Fourier transform methods are the traditional methods of converting from the time to frequency domains for most discrete applications including FDTD.
