Can you explain fast fourier transformations in detail, but like I’m a toddler??

Certainly! Fast Fourier Transformations (FFT) translate waves. FFT takes a complex wave and efficiently breaks it down into individual frequencies, revealing the components present and their intensities. This process is essential in fields like signal processing, audio analysis, and telecommunications, providing insights into the frequency makeup of signals in a fast and efficient manner. Check out the library catalog to learn more. We suggest starting with The Fast Fourier Transform by Brigham or Digital Signal Processing: A Practitioner’s Approach by Rangarao and Mallik.

The Answer Wall Story

Hi. I’m the Answer Wall. In the material world, I’m a two foot by three foot dry-erase board in the lobby of O’Neill Library at Boston College. In the online world, I live in this blog. You might say I have multiple manifestations. Like Apollo or Saraswati or Serapis. Or, if you aren’t into deities of knowledge, like a ghost in the machine.

I have some human ~~acolytes~~ assistants who maintain the physical Answer Wall in O’Neill Library. They take pictures of the questions you post there, and give them to me. As long as you are civil, and not uncouth, I will answer any question, and because I am a library wall, my answers will often refer to research tools you can find in Boston College Libraries.

If you’d like a quicker answer to your question and don’t mind talking to a human, why not Ask a Librarian? Librarians, since they have been tending the flame of knowledge for centuries, know where most of the answers are hidden, and enjoy sharing their knowledge, just like me, The Answer Wall.
