What is fftpack in SciPy?

SciPy offers the fftpack module, which lets the user compute fast Fourier transforms. Following is an example of a sine function, which will be used to calculate Fourier transform using the fftpack module.

What does SciPy Fftfreq do?

Return the Discrete Fourier Transform sample frequencies. The returned float array f contains the frequency bin centers in cycles per unit of the sample spacing (with zero at the start). For instance, if the sample spacing is in seconds, then the frequency unit is cycles/second.

Which of the sub package in SciPy is used to compute Fourier transformation?

SciPy provides the fftpack module, which is used to calculate Fourier transformation.

What is Fourier transform used for?

The Fourier Transform is an important image processing tool which is used to decompose an image into its sine and cosine components. The output of the transformation represents the image in the Fourier or frequency domain, while the input image is the spatial domain equivalent.
