"Compression and Quantization Encoding, often abbreviated as CQE, is a fundamental concept in digital signal processing and data compression techniques. It involves reducing the size of digital data by converting it into a more compact form through mathematical algorithms. This method combines two key steps: compression, where unnecessary or redundant information is removed, and quantization, which replaces continuous values with discrete ones, often using fewer bits. For instance, in image or audio coding, CQE is employed to create efficient file formats like JPEG for photos or MP3 for music. An example sentence could be: "To efficiently store high-resolution images, the engineers employed advanced CQE algorithms, resulting in significantly smaller file sizes without compromising quality."
