How do you convert frequency domain to time domain?
Each component in the frequency domain is a sine wave in the time domain, defined from t = - infinity to t = + infinity. To re-create the time-domain waveform, we take each of the sine waves described in the spectrum and add them up in the time domain at each time-interval point.
Why do we convert frequency domain to time domain?
Time domain signal processing enables an engineer to separate extraneous signals in time from the desired signal, thereby identifying the contaminated signals. In general, using a frequency domain will simplify analysis mathematically for the system running it.
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.
What is the benefit of converting a time domain signal into a frequency domain signal?
The principal benefit of converting the time domain signal to a frequency domain signal is to understand the frequency components and to get the power spectral density. (The spectral energy in the signal is the fft as you have calculated and plotted it in figure(3).
