Signal processing is the art of representing, transforming, analyzing, and manipulating signals. It deals with a wide range of signals, from speech and audio signals to images and video signals, and many others. Signal processing techniques have been found very useful in diverse applications. Traditional applications include signal enhancement, denoising, speech recognition, audio and image compression, radar signal processing, and digital communications, just to name a few. In recent years, signal processing techniques have been also applied to the analysis of biological data with considerable success.
信號處理代表，轉換，分析和操作信號的藝術。它處理多種信號，從語音信號和音頻信號對圖像和視頻信號，和許多其他。信號處理技術已經被發現在不同的應用中非常有用。傳統的應用包括信號增強，降噪，語音識別，音頻和圖像壓縮，雷達信號處理，和數字通信，僅舉幾例。在最近幾年，信號處理技術已經被也加到與相當大的成功的生物數據的分析。
