What is Digital Signal Processing?
Digital Signal Processing (DSP) involves the manipulation of signals after they are converted from analog to digital form. It encompasses a broad range of techniques used to analyze, modify, and optimize signals for various applications. Unlike analog processing, DSP offers higher accuracy, flexibility, and ease of implementation, making it a cornerstone of modern technology.
Core Concepts of DSP
- Sampling: Converting continuous signals into discrete signals.
- Quantization: Approximating the sampled signals to finite levels.
- Filtering: Removing unwanted components or enhancing desired features.
- Transformations: Using Fourier, Laplace, or Z-transforms for frequency analysis.
- System Design: Creating algorithms and hardware for real-time processing.
