[讨论] 强烈推荐一本数字信号处理的入门好书

Suppose you encounter a DSP problem, and turn to textbooks or other publications to find a solution. What you will typically find is page after page of equations, obscure mathematical symbols, and unfamiliar terminology. It's a nightmare! 

说一说书名吧？？？如果你有资源的话也可以分享上来

英文版的，两年看不了一本。
