求简单微分方程的解析解，．求微分方程的数值解，数学建模实例。(Seeking simple differential equations, analytical solution. The numerical solution of seeking differential equations, mathematical modeling instance.)

This book is about signal processing, which includes processes for synthesizing, transforming, and analyzing signals. It focuses on sound signals, but the same methods apply to other signals, like electronic signals and mechanical vibration.
