我赞同 Lyons 那本。另外，Steven Smith 的《Digital Signal Processing: A Practical Guide》也很通俗易懂——不需要深厚的微积分功底。Ken Steiglitz 的《A Digital Signal Processing Primer》是一本优秀但严谨的入门书。由 EE 学者撰写，在数学严谨性上超过了 Smith 或 Lyons。Allen Downey 的《Think DSP》也值得一读，不过……
I second Lyons. In addition, "Digital Signal Processing: A Practical Guide" by Steven Smith is also quite approachable -- immersion in calculus not required. "A Digital Signal Processing Primer" by Ken Steiglitz is a nice but rigorous intro to the subject. Written by an EE academic, it's more mathematically rigorous than Smith or Lyons. Allen Downey's "Think DSP" is also worth a look, though…
……数学，附带的可视化有助于直观理解 DFT 对其输入做了什么。虽然我会推荐涵盖该主题的教材，比如 Ken Steiglitz 的《A Digital Signal Processing Primer》，但 Gemini 只要用下面这句 prompt 就能显示 DFT 窗函数的响应图：“what is the z transform of the hamming window in a discrete fourier transform context”
…mathematics the attendant visualizations can be helpful to impart an intuitive understanding of what the DFT is doing with its inputs. While I would recommend a text that covers the topic such as "A Digital Signal Processing Primer" by Ken Steiglitz, Gemini was able to show the response graph of a DFT window function with the following prompt: "what is the z transform of the hamming window in a discrete fourier transform context"
