Signal Processing

Signal processing is a technology that studies, analyzes, and manipulates signals to extract useful information or enhance signal quality. Its objectives include the detection, estimation, filtering, and coding of signals, aiming to improve the interpretability and transmission efficiency of signals. Signal processing has significant application value in fields such as communications, radar, biomedicine, and image processing, effectively addressing issues like noise suppression, data compression, and feature extraction. Audio signal processing, as one of its branches, focuses specifically on the processing and analysis of sound signals.
