"Python for Signal Processing" is a technical book that addresses the fundamental concepts of signal processing and illustrates them through Python code. The content is integrated into IPython Notebooks, which are interactive, browser-based documents. These allow readers to change parameters, redraw graphs, and experiment with the ideas presented in the text. The book focuses on the core principles of signal processing and provides a computable environment that invites experimentation and learning. It is aimed at both individuals who wish to migrate their existing signal processing codes to Python and those who are already familiar with the scientific Python toolchain and want to deepen their knowledge of signal processing.
