A mathematical theorem stating that a periodic function f(x) which is reasonably continuous may be expressed as the sum of a series of sine or cosine terms (called the Fourier series), each of which ...

While the Fourier transform gets all the attention, there are other transforms that engineers and mathematicians use to transform signals from one form to another. Sometimes you use a transform to ...

The FFT/IFFT/DCT engine is an application specific instruction set processor (ASIP) optimized for the implementation of Fourier and cosine transforms, while also supporting general FIR equations. ...
