Frequency Domain Graph
I wanted to convert the graph in the top red box for the frequency domain to the graph in the bottom red box for the time domain.
Frequency domain graph. A frequency domain representation can also include information on the phase shift that must be applied to. In physics electronics control systems engineering and statistics the frequency domain refers to the analysis of mathematical functions or signals with respect to frequency rather than time. Any graph which plots time on one axis and amplitude on the other shows you the signal in the time domain.
Spectrum plots are particularly useful for representing sounds because sound mostly consists of vibrations that are quasi periodic and complex. Hello i have calculated the time domain of the hanning window through the formula. 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.
Frequency domain analysis is widely used in such areas as communications geology remote sensing and image processing. Put simply a time domain graph shows how a signal changes over time whereas a frequency domain graph shows how much of the signal lies within each given frequency band over a range of frequencies. N m 2.

What should i do. I converted it to frequency domain by using fft in matlab. Once you know the fundamental frequency and the coefficients of the fourier series you can graph any complex wave in a frequency domain aka frequency spectrum and completely describe that wave.
For those not familiar with the frequency domain this article will give a good introduction of what exactly the meaning of frequency domain is. Most of the graphs you have seen are in the time domain. Hanning window frequency domain graph.
