Discrete Fourier Transform
>> YOUR LINK HERE: ___ http://youtube.com/watch?v=W30U_rcThLg
In this video we discuss the Discrete Fourier Transform (DFT). We provide some background, discuss the general concept, and derive the DFT from first principles. We then show how to compute it using a concrete example. Future lectures will build on this to discuss applications of the DFT such as frequency spectrum analysis. • Topics and timestamps: • 0:00 – Introduction • 3:35 – Nth Roots of Unity • 7:44 – Derivation of the DFT • 46:31 – Example • 1:00:42 – Interpreting the results • Lecture notes and code can be downloaded from https://github.com/clum/YouTube/tree/... • All Fourier analysis videos in a single playlist ( • Fourier Analysis ) • #FourierAnalysis #FourierSeries • You can support this channel via Patreon at / christopherwlum or by clicking on the ‘Thanks’ button underneath the video.
