Hi all,I got an FPGA design running #FFT at 256 points. Our system requires fft be configured as either 256 or 512 points on the run. I can use variable fft that...

Hello,I have an algorithm that slices wav file into blocks (frames) of size 64 and does 64 point FFT on them. Recently I was give a hardware acceleration library...

I am working on an accelerometer with sampling rate of 26.7 kHz on which I intend to calculate FFT. Hence the FMax =  (26.7/2.56 = 10.4kHz). As I am performing...

Hi all,Suppose I have an input signal \( x[n] \) of length \( N \), an FIR filter \( h[n] \) of length \( M \), and a window function \( w[n] \) of length \( N...

Note: I posted this question on Signal Processing Stack Exchange yesterday. Because the one answer I got so far was not-so-satisfying, although surely well-intentioned,...

Hi AllDoes anyone have experience with the #ARM CMSIS #FFT? Specifically the floating point implementation arm_cfft_f32()?Although testing the code using the ARM...

I would like to down sample a signal from it's original sampling rate of 2,000,000 samples per second to 48,000 (or 44100) starting from the output of an #FFT.  This...

Hello everyone. I need some advice regarding 3D #FFT on #Matlab. My signal is represented as a 3D matrix (Let's say 10x10x10) I wanted to find the fft and then...

First of all, let me warn you, I'm a neophyte on this. Did my EE degree 40 years ago, before FFT's were rediscovered.I am trying to reduce frequency bin "leakage"...
