You'd get better help with a better explanation of what you need. You don't even say what assembly language, for instance. Also, it would help to know the purposeare you really trying to just get the FFT of only a sine wave? There are plenty of FFTs in C on the web.Hi i need the code in assemble language or C code for finding the FFT of Sine wave..Please help me
Fast Fourier Transform. It's a DFT (Discrete Fourier Transform, as in discrete time—useful for processing samples in the digital domain in other words), that has been optimized by eliminating some redundant calculations so that as the number of samples doubles, the required calculations don't (they are related to the log of that number, so it's a huge win for longer transforms).What is FFT?
A few examples:What would be some practical applications for FFT?
I use FFT quite frequently for noise analysis. Lots of times, noise an a signal looks "random", but passing it through an FFT often shows discrete peaks that correspond to noise sources in other parts of the system. This assists in making changes that attenuate interference from those parts of the system.
LOL I said for 'normal' people.I use FFT quite frequently for noise analysis.

ROFLI take it you're joking. The FFT is one of the most widely used numerical algorithms on the planet. It's used in image processing (ever seen Photoshop?) music and recording gear of many types, video, electronics test gear.
Well at least that's something.You could not do MRI scans without FFT.
CT scans uses X-ray radiation. MRI scans do not use ionizing radiation.Most things show up on a CT scan that are within 1mm. In Australia, we don't bother with MRI much, because the benefits don't out weigh the risks and the associated costs when a CT scan can usually suffice.
If you have ever done any metal work in your life, then you are at potential risk with having some complications after having an MRI scan.CT scans uses X-ray radiation. MRI scans do not use ionizing radiation.
