The A-law algorithm is a standard companding technique used in digital communication systems, particularly in systems that process audio signals. It is primarily employed in the European telecommunications network and is a part of the ITU-T G.711 standard. ### Purpose: The A-law algorithm compresses and expands the dynamic range of analog signals to accommodate the limitations of digital transmission systems. By reducing the dynamic range, it effectively minimizes the impact of noise and distortion during transmission.
