《Understanding Digital Signal Processing》的价值不在于提供新的理论发现,而在于重构了教学范式。Lyons成功地将抽象的信号处理转化为可视化的工程直觉,这对于应用层工程师至关重要。然而,其局限性也显而易见:为了可读性,他刻意回避了严格的数学证明,这使得本书无法独立支撑起一个完整的DSP知识体系。它更像是一座桥梁,连接着零基础与进阶研究,而非终点站。如果你只读这一本,可能会陷入‘懂了但不会推’的困境;但若将其作为第一本入门书,它能极大缓解初学者的焦虑感。
"First, a bit of trivia. As you know, it is a digital computer, not a digit computer. The information processed is called digital data, not digit data. Why then, is analog-to-digital conversion generally called: digitize and digitization, rather than digitalize and digitalization? The answer is nothi"
