Workshop 2.3 You Try Meow (Miauw)

The goal of this workshop to work with the Discrete Fourier Transform (DFT), implemented in Python as the Fast Fourier Transform (FFT) through np.fft.fft, and to understand and interpret its output.

To start off, let’s do a quick quiz question: what is the primary purpose of the DFT? Preview this file (and enable external content) to see the question below.

That’s right! We convert our signal into the frequency domain.

And if you would like an additional explanation of the key frequencies, you can find it here.
