Digital signal processing (DSP) refers to the manipulation of signals that have been converted from analog to digital form. Signals can represent a variety of data types, including audio, video, images, and sensor readings. The conversion to digital form allows for the application of mathematical algorithms and techniques to analyze, modify, or enhance the signals. ### Key Concepts: 1. **Sampling**: The process of converting an analog signal into a digital signal by taking discrete samples at regular intervals.
