Cоmpаre аnd cоntrаst time-dоmain sensor signals with frequency-domain representations. Explain how Fast Fourier Transforms (FFT) are used on edge devices to perform spectral analysis. From a systems engineering perspective, why is spectral analysis highly preferred as a digital signal processing (DSP) preprocessing step before feeding features into a machine learning classifier on deeply resource-constrained microcontrollers?
