1024 pipelined FFT algorithm
no vote
FFT discrete Fast Fourier transform algorithm, a signal can be transformed To the frequency domain. Is difficult to see what some signals in the time domain characteristics, but transformed to the frequency domain, it is easy to see that feature. This is the reason why many signal analysis based on FFT transform. In addition, FFT frequency spectrum of a signal can be extracted, it is also often used in spectrum analysis. While many people know that the FFT is, what can you do, how to do it, but don't know what after FFT results mean, how do you decide how many points do you want to use FFT. Specific frequency multiplication method can refer to the related documents.
