    Respected author

    You have done an excellent job by providing a masterpiece of work in the form of Intuitive Guide to Fourier Analysis and Spectral Estimation book. It is really an excellent text on the claimed topic.

    Wonderful explanation with beautiful figures. Simply beautiful. Waiting for more such useful text in future. Keep it up.

      So very touching of you to say that. I am humbled by it! Thank you.
      I hope you purchased the book on Amazon. In Kindle it is quite inexpensive.
      Thank you very much again for your kind words – Charan

    Charan,
    I have read enough of your tutorials to know that your book will be excellent but you need to add a link to places that sell it. 🙂
    Thank you for providing Matlab to go with it. For anyone who doesn’t have or can’t afford Matlab, Scilab is an open source alternative that can run all Matlab code. This is a link to it http://www.scilab.org/.
    Freemat is another Malab clone but I don’t know as much about it (http://freemat.sourceforge.net/)

    Any chance of getting the answers to the book questions?

    Also, will there be an update to the ebook if you’ve already purchased?

    Great book so far…love it.

    • Charan L. says:

      John,
      Since the book is being used as a text book, I am asked not to provide the answers on the open forum. The questions are actually designed to be pretty simple. Perhaps, I will create a page, where students can post their answers.

      Thanks a bunch for letting me know, you liked the book. I have looked into how to provide update to the Kindle eBook but really can not figure out a way to do that. Amazon does not offer updates of Kindle eBooks. I wish they would let you download the latest version.

      Thanks again,
      Charan

        Excellent book! However, as having to learn on my own, I find it frustrating that all those question pages are left without answers. If a teacher is using it as a textbook it would be a wonderful help for his/her students to prepare for exams IF answers were given. You may think they are simple. Everything is simple for those who already know the topic. All the questions may or may not be simple for all readers. Anyway, the learning curve would be less steep for most readers if answers were provided, and any professional teacher should be able to write variations of the questions instead of just copying your Question-pages. I am unfortunately in the group who needs to know if my answers are correct. The teachers should not need your help. Many students do.

  7. John says:

    Thanks for the response.

    I didn’t know the book was going to be a “text” book as it didn’t seem to be styled like one so I thought I’d ask about the answer sheet. Sometimes it’s frustrating trying to do a problem and not knowing whether you got it correct…hence the inquiry.

    BTW, it’s refreshing to read about the Fourier transforms the way you’ve presented it. Many books don’t even mention the DTFT or if they do they don’t distinguish it from the others in a clear manner. Hence, many texts end up just making it more confusing than it needs to be. You’ve done a terrific job clearing most of that up.

    Thanks!

    Hi Dr Langton
    Would you be able to advise me when your book will be available in hard copy.

    I’ve read some introductory chapters and I must say, the book is very well written. Keen to have a copy.

    • Charan L. says:

      The book will be available end of this month. Look on Amazon around June 10th.
      I am glad you like it. Appreciate your saying so.
      Thank, Charan

    I just bought this book in hardcover–I like the color graphs. They make the waveforms easier to see and understand. I have two questions: 1) Why no index? As a reference book, it really needs one. 2) When will you publish the MatLab code?

    • Charan L. says:

      Hello Mike,
      The code is here on the website, perhaps a bit hard to find. Here is the link.

      The index will be added back in the next printing. We were initially going to do the book only in Kindle, which has searching capabilities and hence index is superfluous. So I guess in the next version, we will put the index back. I might add it on online here first. I will let you know when I do that. Thanks for your comments. Hope the book is useful to you.
