Signal processing is a cornerstone of modern technology, enabling everything from high-quality audio streaming to advanced medical imaging. It involves analyzing, modifying, and synthesizing signals like sound, images, and electromagnetic waves.
Key Techniques
- Fourier Transform: Decomposes signals into their frequency components.
- Filtering: Removes noise or enhances certain features in a signal.
- Sampling: Converts continuous signals into discrete data.
Everyday Applications
- Enhancing speech in phone calls.
- Compressing images and videos for storage.
- Detecting abnormalities in ECG signals.
Whether you're an engineer or just curious about the tech around you, signal processing is a field worth exploring for its immense practical impact.
