Digital signal processing

DSP converts real-world analog signals into mathematical sequences for high-speed manipulation, filtering, and compression.

Digital Signal Processing (DSP) is the computational engine behind modern telecommunications and media. By digitizing continuous waveforms (like sound or radio waves) into discrete numbers, DSP enables real-time operations such as noise cancellation in AirPods, image sharpening in smartphone cameras, and data multiplexing in 5G networks. It relies on specialized hardware like Texas Instruments TMS320 processors and algorithms such as the Fast Fourier Transform (FFT) to execute millions of operations per second with minimal latency. From medical MRI reconstruction to deep-sea sonar, DSP provides the precision required to extract signal from noise.
