Why time domain is converted to frequency domain?
For mathematical systems governed by linear differential equations, a very important class of systems with many real-world applications, converting the description of the system from the time domain to a frequency domain converts the differential equations to algebraic equations, which are much easier to solve.
How do you convert time to frequency in fft?
Note that for the FFT the spectral resolution (in Hz) is the inverse of the overall width of your time vector (so 100 secs --> 0.01 Hz). The width of your spectrum is the inverse of your timestep (so 0.1 sec --> 10 Hz (-5 Hz ... 5 Hz).
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.
