4096), in hardware with very low latencies. The core ... The FFT1-32-512/4 core implements 32, 64, 128, 256, and 512 point FFT and IFFT in hardware that runs at the clock frequency four times higher ...

so that there are 16 exponent values for this 256-point FFT. During the last stage of the computation, full floating-point is used, so that the “fixed-point” design actually produces an output data ...

Figure 1 There are 4096 data samples from a 12-bit converter in this FFT plot. The frequency spectrum for a 4096-point FFT is 100 kHz with f IN =9.9 kHz. The specifications of interest in an FFT plot ...

If speed of computation is an issue we can constrain our sample points to powers of two and get a large speed advantage.Generally I find that the difference from say a decently sized FFT of 8192 ...

Both methods used the same 2048-point data set. The FFT features a resolution of 4 Hz/bin, while the HRFT, calculated for 41 points, has a resolution of 0.2 Hz/bin. This is evident in the ...

Say we have a signal sampled at f s 1 = 1024 kHz, and we require 2 kHz FFT bin spacing for our spectrum analysis resolution. These conditions require us to collect 512 samples (1024 kHz/2 kHz) and ...
