Simplifying Signal Processing with Fourier Transform
The chapter delves into practical applications of streams, multiplication, convolution, and Fourier transform in simplifying complex mathematical operations related to signal processing. It explains the transition from traditional Fourier transform to digital signal processing, introduction of Discrete Fourier Transform (DFT), and the importance of sampling in signal conversion. Furthermore, it discusses the efficiency improvements made by mathematicians Cooley and Tukey in the development of the Fast Fourier Transform (FFT) and the significance of choosing the right sampling frequency for accuracy in signal processing.
