What is Fourier transform in mathematics?

Fourier Transform is a mathematical model which helps to transform the signals between two different domains, such as transforming signal from frequency domain to time domain or vice versa. Fourier transform has many applications in Engineering and Physics, such as signal processing, RADAR, and so on.

How do you explain Fourier transform?

The Fourier transform is a mathematical function that decomposes a waveform, which is a function of time, into the frequencies that make it up. The result produced by the Fourier transform is a complex valued function of frequency.

What is Fourier analysis in simple terms?

Fourier analysis is a type of mathematical analysis that attempts to identify patterns or cycles in a time series data set which has already been normalized. In particular, it seeks to simplify complex or noisy data by decomposing it into a series of trigonometric or exponential functions, such as sine waves.

What is the principle of Fourier transform?

Fourier transform spectroscopy is a technique that uses interference of light rather than dispersion to measure the spectrum of a substance. The basis of this technique is the Fourier-pair relationship between the interferogram (interference function) of a substance and its spectrum.
