Introduction to fft
WebI am looking for a great introduction to FFTs for my job. I studied math, but never heard of FFT until I got this job. There is not a lot of documentation at my place of work and the articles I have found online have been somewhat confusing, even the wikipedia entry. So I am looking for a recomendation for a higher level introduction to FFT. WebThe Fast Fourier Transform (FFT) is an efficient algorithm to calculate the DFT of a sequence. It is described first in Cooley and Tukey’s classic paper in 1965, but the idea …

To understand the output of FFT, let’s create a simple sine wave. The following piece of code creates a sine wave with a sampling rate = 100, amplitude = 1 and frequency = 3. Amplitude values are calculated every 1/100th second (sampling rate) and stored into a list called y1.
