Fourier Analysis
Fourier analysis of spatial and temporal visual stimuli has become common in the last 35 years. For many people interested in vision but not trained in mathematics this causes some confusion. It is hoped that this brief tutorial, although incomplete and simplified, will assist the reader in understanding the rudiments of this analytic method. At the outset, I would like to acknowledge the valuable e-mail exchanges I had with Dr. D.H. Kelly. Although I obviously must take responsibility for any errors or misconceptions that still remain, I am grateful to Dr. Kelly for helping me to present these difficult concepts intuitively and accurately. The purpose of this section of the book is to familiarize readers with these concepts so that they will not be entirely new and strange when encountered in hardcopy textbooks. A second reason, aimed at students in the early stages of their educational career, is to encourage them to take the appropriate mathematics courses so they can become proficient in the use of Fourier and allied methods. Before proceeding, let's understand one important point. The use of these Fourier methods does not mean that the visual system performs a Fourier analysis. At present it should be understood that this approach is a convenient way to analyze visual stimuli.

FOURIER ANALYSIS The representation of a PERIODIC sound or WAVEFORM as a sum of Fourier components (i.e. pure SINUSOIDAL WAVE s). According to the FOURIER THEOREM , periodic sound may be shown to consist of SINE WAVE s in the HARMONIC SERIES , where the Fourier coefficients give the AMPLITUDE and PHASE angle of each component. Fourier analysis may be performed mathematically if the expression f(t) describing the waveform or COMPLEX TONE is known, or else by converting the sound to digital form by a computer which then analyzes it. The average SPECTRUM of an instrument may be obtained in this way by analyzing it during a representative section of its STATIONARY STATE . However, if every period of the sound is analyzed, it will be seen that the spectrum is always changing in time, i.e. the harmonic components in the spectrum are constantly changing in amplitude. A more general form of analysis for transferring a time-domain signal to the frequency domain is called the Fourier transform.

You can vary the amplitude and phase of any of these signals and add them up to generate a complex wave form. The output goes to an oscilloscope and also to a speaker so the class can hear the wave form. The two fundamentals can be added alone to show the sum of two sine waves, or sent to two speakers to demonstrate acoustical interference. The Fourier analyzer shows the power spectrum of a complex wave form on an oscilloscope.

Fourier analysis is fundamental to understanding the behavior of signals and systems. This is a result of the fact that sinusoids are FIX ME - Eigenfunctions of linear, time-invariant (LTI) systems. This is to say that if we pass any particular sinusoid through a LTI system, we get a scaled version of that same sinusoid on the output. Then, since Fourier analysis allows us to redefine the signals in terms of sinusoids, all we need to do is determine how any given system effects all possible sinusoids (its transfer function ) and we have a complete understanding of the system. Furthermore, since we are able to define the passage of sinusoids through a system as multiplication of that sinusoid by the transfer function at the same frequency, we can convert the passage of any signal through a system from

    B C D ... General Computing Terms Fourier analysis
    Fourier analysis is a method of defining periodic waveform s in terms of trigonometric function s. The method gets its name from a French mathematician and physicist named Jean Baptiste Joseph, Baron de Fourier, who lived during the 18th and 19th centuries. Fourier analysis is used in electronics, acoustics, and communications. Many waveforms consist of energy at a fundamental frequency and also at harmonic frequencies (multiples of the fundamental). The relative proportions of energy in the fundamental and the harmonics determines the shape of the wave. The wave function (usually amplitude , frequency, or phase versus time ) can be expressed as of a sum of sine and cosine function s called a Fourier series , uniquely defined by constants known as Fourier coefficient s. If these coefficients are represented by

    Table of Contents
    Chapter 1 [in PDF format]
    This first volume, a three-part introduction to the subject, is intended for students with a beginning knowledge of mathematical analysis who are motivated to discover the ideas that shape Fourier analysis. It begins with the simple conviction that Fourier arrived at in the early nineteenth century when studying problems in the physical sciencesthat an arbitrary function can be written as an infinite sum of the most basic trigonometric functions. The first part implements this idea in terms of notions of convergence and summability of Fourier series, while highlighting applications such as the isoperimetric inequality and equidistribution. The second part deals with the Fourier transform and its applications to classical partial differential equations and the Radon transform; a clear introduction to the subject serves to avoid technical difficulties. The book closes with Fourier theory for finite abelian groups, which is applied to prime numbers in arithmetic progression. In organizing their exposition, the authors have carefully balanced an emphasis on key conceptual insights against the need to provide the technical underpinnings of rigorous analysis. Students of mathematics, physics, engineering and other sciences will find the theory and applications covered in this volume to be of real interest.

    Fourier analysis
    A mathematical analysis that attempts to find cycles within a time series of data after detrending the data. For example, a Fourier analysis can be done on a time series of price data for a product over twenty years, but only after the effects of inflation are removed, thereby detrending the data.

    Fourier Analysis
    Why frequency analysis?
    • Many signals in the natural environment are conveniently described in terms of a superposition of wobbly functions (e.g., many sounds are produced by vibrating membranes).
    • Sines and cosines are eigenfunctions of linear, time-invariant systems. Thus, they can be used to conveniently characterize the response of a linear system. Also, convolution, which is a complicated signal transformation in the time or space domain, is performed by simple multiplication in the frequency domain.
    The Fourier series
    • What is remarkable about this is that can be anything- the waveform produced by a bird chirping, the sound of your dishwasher, electromagnetic waves, etc.
    • The amplitudes tell you how much of each frequency is present in the signal. For example, a pure tone (e.g., the waveform emitted by a tuning fork) would have
    • A to assign to each f . For this we need the Fourier transform
    The Fourier transform
    • The Fourier transform basically provides a way of representing a signal in a different space - i.e., in the frequency domain . You put into the Fourier transform a function of time or space

    Fourier Analysis
    A real wavefunction can be decomposed into a sum of harmonic terms using the technique of Fourier analysis. With fixed boundaries this decomposition becomes where N is the number of points on the space grid, L is once again the length of the medium, and n is referred to as the bin number. With periodic boundaries, both and terms are present in the decomposition. For real the Fourier analysis graph will display either for fixed boundaries or for periodic boundaries. Expansion coefficients for a function defined on a uniform grid can be obtained very efficiently using a numerical technique called the Fast Fourier Transform, FFT. It is discussed in detail in Chapter 2 and has been implemented in WAVE
