Most engineers don’t remember the complex algorithms and concepts of the Fast Fourier Transform (FFT) and Discrete Fourier Transform (DFT) that they learned in college. Instead of dusting off your textbooks, check out this Fast Fourier Transform visual from Tektronix. It boils down the key tips and practical knowledge for Engineers and their designs. With this visual, we hope you can skip digging up your old text books and get back to your designs.
