Fourier and FFT Concepts in Circuit Design - Part 2 (ECE Topics #8)

Episode 8 covers Fourier Series and Fast Fourier Transform (FFT) concepts with a focus on applications. Part 1 ( • Fourier and FFT Concep... ) introduced time and frequency domain characterization of signals using guitar sounds, and touched briefly on extending the theory to applications in wireless communications. A Rigol DHO 800 series scope was used to show real-world audio waveforms and spectrums, and interpretation of the FFT display was presented in some depth. This part 2 video focuses on circuits and signal processing, and how designers use these concepts to realize response-shaping circuits and filters to achieve system level goals.
