Use Fourier transforms to find the frequency components of a signal buried in noise.

Specify the parameters of a signal with a sampling frequency of 1 kHz and a signal duration of 1.5 seconds.
Form a signal containing a 50 Hz sinusoid of amplitude 0.7 and a 120 Hz sinusoid of amplitude 1.
Corrupt the signal with zero-mean white noise with a variance of 4.
Plot the noisy signal in the time domain. It is difficult to identify the frequency components by looking at the signal
X(t) .

Compute the Fourier transform of the signal.
Compute the two-sided spectrum
P2 . Then compute the single-sided spectrum P1 based on P2 and the even-valued signal length L .
Define the frequency domain
f and plot the single-sided amplitude spectrum P1 . The amplitudes are not exactly at 0.7 and 1, as expected, because of the added noise. On average, longer signals produce better frequency approximations.
Now, take the Fourier transform of the original, uncorrupted signal and retrieve the exact amplitudes, 0.7 and 1.0.
Convert a Gaussian pulse from the time domain to the frequency domain.
Define signal parameters and a Gaussian pulse,
X .
Plot the pulse in the time domain.
To use the
fft function to convert the signal to the frequency domain, first identify a new input length that is the next power of 2 from the original signal length. This will pad the signal X with trailing zeros in order to improve the performance of fft .
Convert the Gaussian pulse to the frequency domain.
Define the frequency domain and plot the unique frequencies.
Compare cosine waves in the time domain and the frequency domain.
Specify the parameters of a signal with a sampling frequency of 1kHz and a signal duration of 1 second.
Create a matrix where each row represents a cosine wave with scaled frequency. The result,
X , is a 3-by-1000 matrix. The first row has a wave frequency of 50, the second row has a wave frequency of 150, and the third row has a wave frequency of 300.

Plot the first 100 entries from each row of
X in a single figure in order and compare their frequencies.
For algorithm performance purposes,
fft allows you to pad the input with trailing zeros. In this case, pad each row of X with zeros so that the length of each row is the next higher power of 2 from the current length. Define the new length using the nextpow2 function.
Specify the
dim argument to use fft along the rows of X , that is, for each signal.
Compute the Fourier transform of the signals.
Calculate the double-sided spectrum and single-sided spectrum of each signal.
In the frequency domain, plot the single-sided amplitude spectrum for each row in a single figure.
Check out Journey of the Five.
It's truly a full hack of FFT; not just a mod. A full story hack with all new sprites. The five main characters, Ramza, Cloud, Link (LoZ), Snake (Metal Gear) and Dante (Devil May Cry). Are entangled into a strange cross-over type adventure. Full of challenging battles and great new characters with special abilities. It also features all new events or cut-scenes, which are full of vagaries. All the events are slavishly produced by Elric from ffhacktics.com. It features all new sprites for the characters even most of the generic classes are remade (about 90% of em). Twinees, Kage, I and others (Choto worked a good amount on a great enemy sprite [no spoilers here]) all worked hard on those. Chapter 1 is already avalable for download and enjoyment here: JOT5 Chapter 2 is almost available for enjoyment but there's a minor dilemma. Two sprite sheets are incomplete which is preventing it's release. All of the events are done and I think everything's pending only because of that factor. Yet most of us spriters from FFH have been too busy to do much about them lately. So if anyone cares to step in and try a hand at making pro level. [yes, you heard correctly] pro level, or at least close!. Please! Join the Jot5 team; finish two sprite sheets. it's actually pretty enjoyable to see your own sprites in a hack like Journey of the Five! Let all the folks who've played Ch. 1 and hunger for the pending next chapter rejoice. Here is the first youtube demo vids posted after Ch.1 came out (or one of the first): If you want to volunteer to make a sprite or two for this project please join the forum here: ffhacktics.com/smf/indeā¦ And just send the project leader, Elric a private message.. Or you could PM me here first. Here are a couple custom sprites I posted here used in the game: geo __geo_
