The book "Quantization Error" by Betascript Publishing offers a comprehensive analysis of the concept of quantization error, which is central to digital signal processing and telecommunications. It addresses the difference between the actual analog value and the quantized digital value that arises from rounding or truncation. This deviation is referred to as quantization noise, a model that describes the nonlinear and signal-dependent characteristics of the error. The book is a valuable resource for professionals and students seeking a deeper understanding of the challenges and models related to analog-to-digital conversion. It provides high-quality content based on Wikipedia articles, making it a solid foundation for studying quantization in various applications.
