Output: another sequence of complex numbers such that:Intuitively, this means that we are braking up the complex signal into sinusoidal frequencies:and is the amplitude of each sine.
- : is kind of magic and ends up being a constant added to the signal because
- : sinusoidal that completes one cycle over the signal. The larger the , the larger the resolution of that sinusoidal. But it completes one cycle regardless.
- : sinusoidal that completes two cycles over the signal
- ...
- : sinusoidal that completes cycles over the signal
Motivation: similar to the Fourier transform:In particular, the discrete Fourier transform is used in signal processing after a analog-to-digital converter. Digital signal processing historically likely grew more and more over analog processing as digital processors got faster and faster as it gives more flexibility in algorithm design.
- compression: a sine would use N points in the time domain, but in the frequency domain just one, so we can throw the rest away. A sum of two sines, only two. So if your signal has periodicity, in general you can compress it with the transform
- noise removal: many systems add noise only at certain frequencies, which are hopefully different from the main frequencies of the actual signal. By doing the transform, we can remove those frequencies to attain a better signal-to-noise
Sample software implementations:
- numpy.fft, notably see the example: numpy/fft.py
DFT of with 25 points
. This is a simple example of a discrete Fourier transform for a real input signal. It illustrates how the DFT takes N complex numbers as input, and produces N complex numbers as output. It also illustrates how the discrete Fourier transform of a real signal is symmetric around the center point.Saudi Arabian physicists are scientists from Saudi Arabia who specialize in the field of physics. They can work in various areas such as theoretical physics, experimental physics, condensed matter physics, astrophysics, and many other sub-disciplines. The kingdom has invested significantly in education and research, leading to the development of institutions such as King Abdullah University of Science and Technology (KAUST) and King Saud University, which have contributed to advancements in various scientific fields.
Yasumasa Kanada is a renowned Japanese mathematician and computer scientist, best known for his contributions to the field of numerical analysis and the study of algorithms. He is particularly recognized for his work in the field of computation of mathematical constants, including π (pi). Over the years, Kanada has been involved in various projects that utilize high-performance computing, and he is known for setting several records for the fastest calculations of π.
The IMDb of music! They actually have a reputation system apparently. And sneaked in a vinyl marketplace as well.
The website name sounds like play on words: disc + hog, with hog in the sense "memory-hog", i.e. something that consumes all your computer's memory.
RUNCOM is a term that typically refers to a configuration file or set of procedures used in various computing environments, particularly in Unix-like systems. The name "RUNCOM" is derived from "run commands." Here are a few contexts in which RUNCOM might be used: 1. **Unix and Unix-like Systems**: In these environments, RUNCOM files are scripts run by the shell during startup. For example, files such as `.bashrc`, `.bash_profile`, or `.
Xiong Qinglai is a renowned Chinese artist known for his work in various forms of visual art, including painting and installation art. His work often explores themes of identity, culture, and the intersection between traditional Chinese art and contemporary practices. Xiong's style can be characterized by a unique blend of traditional techniques with modern concepts, making his pieces both thought-provoking and visually striking.
Pinned article: ourbigbook/introduction-to-the-ourbigbook-project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
