Applications for a new FFT algorithm
Started by 5 months ago●17 replies●latest reply 5 months ago●284 viewsI have invented a new FFT algorithm I'm calling the Lifted Fourier Transform (LFT) ("lifted" because the guts of the method operate in a higher dimension than is...
Radar: Polar to cartesian conversion.
Started by 5 months ago●4 replies●latest reply 5 months ago●200 viewsHi. Something that I have been kicking around for a while is (probably) an Arm based user-side open-source "black box" module to re-use an older ship radar, with...
Processing for realistic animation dynamics
Started by 5 months ago●2 replies●latest reply 5 months ago●97 viewsDear,I have a dynamic animation of the train going up and down like a rollercoaster. Problem is since this animation is choppy and dynamics of the animation is affected. From...
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...

correlation of two complex signals
Started by 6 months ago●19 replies●latest reply 6 months ago●232 viewsI have two complex signals (each a frequency sweep). I need to check delay/advance between them.The first signal is a reference I generate in Matlab. The second...
Hi guys,I wonder if it is possible to get 192kHz samplerate out of a 96kHz ADC.I need to capture a mono signal with 192kHz samplerate. What if I use a 96kHz ADC,...
