Signal Processing

Signal Processing analyzes, modifies, and synthesizes real-world data (sound, images, measurements) to extract essential information and optimize system performance.

This electrical engineering discipline focuses on the mathematical manipulation of signals—like audio streams, medical images, or sensor data—to refine and interpret them. Core techniques include the Fast Fourier Transform (FFT) for shifting data between time and frequency domains, and the design of digital filters (FIR/IIR) to correct distorted signals and suppress noise by millions of times (e.g., in radar). This capability is fundamental to modern technology: it enables 5G telecommunications, powers computer-aided diagnosis in medical imaging (like mammograms), and is critical for object detection in autonomous vehicle radar systems.
