Difference between fft and pspectrum in Matlab
Started by 1 year ago●3 replies●latest reply 1 year ago●678 viewsHello!What is difference between using the fft() or pspectrum() command in Matlab on a time-series signal? My understanding is that the fft command computes the...
Started by 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...
Multiframe FFT using single larger FFT
Started by 2 years ago●4 replies●latest reply 2 years ago●208 viewsHello,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...
Setting required FFT spectrum bandwidth w.r.t the Sampling rate
Started by 2 years ago●4 replies●latest reply 2 years ago●326 viewsI 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...
How to efficiently control an FIR's magnitude response by altering its phase spectrum
Started by 5 years ago●21 replies●latest reply 5 years ago●260 viewsNote: 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,...
ARM CMSIS FFT - does it produce correct results?
Started by 7 years ago●15 replies●latest reply 5 years ago●6441 viewsHi 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...
