Digital Signal Processing&amp;quot; by Steven W. Smith. I spoke to Steven many
years ago about his putting all of the book PDFs online for free and
since then have recommended at least 5 university libraries to buy it
because the students could get free copies of a great book that can be
referenced in the library.&lt;p&gt;FWIW the The Scientist and Engineer&amp;#x27;s Guide doesn&amp;#x27;t actually cover a
lot on sound. It starts in a particular DSP way with frequency domain
definitions and convolution - and I actually think Steven&amp;#x27;s background
is in medial imaging, though I could be mistaken.</text></item></parent_chain><comment><author>WhitneyLand</author><text>Wow.  Such a profound insight could not get published for 15 years because others couldn’t grasp it.  Including Lagrange!&lt;p&gt;It’s an uncomfortable reminder of how essential reputation and credibility are in the machinery of science.&lt;p&gt;&lt;i&gt;”The paper contained the controversial claim that any continuous periodic signal could be represented as the sum of properly chosen sinusoidal waves. Among the reviewers were two of history&amp;#x27;s most famous mathematicians, Joseph Louis Lagrange (1736-1813), and Pierre Simon de Laplace (1749-1827).
While Laplace and the other reviewers voted to publish the paper, Lagrange adamantly protested. For nearly 50 years, Lagrange had insisted that such an approach could not be used to represent signals with corners, i.e., discontinuous slopes, such as in square waves. The Institut de France bowed to the prestige of Lagrange, and rejected Fourier&amp;#x27;s work. It was only after Lagrange died that the paper was finally published, some 15 years later.“&lt;/i&gt;&lt;p&gt;from chapter 8
