Signal resolution refers to the ability of a system to distinguish between different levels of input signals, often determined by the number of bits in digital systems or the bandwidth in analog systems. Higher resolution allows for more precise representation and analysis of signals, crucial in fields like imaging, audio processing, and telecommunications.
Digital Signal Processing (DSP) involves the manipulation of signals to improve or modify their characteristics, enabling efficient data transmission, storage, and analysis. It is fundamental in various applications like audio and speech processing, telecommunications, and control systems, leveraging algorithms to perform operations such as filtering, compression, and feature extraction.
