Clarity on Bit Reversal Sorting
Started by 9 months ago●5 replies●latest reply 9 months ago●129 viewsHello all,I'm going through The Scientist and Engineer's Guide to Digital Signal Processing. I'm currently on Chapter 12 - Fast Fourier Transform.I understand the...
Hello! I am new to DSP and I want to have a board which will have my audio software effect. It will be something like a spectral compressor/limiter and I will experiment...
Good article on Frequency warping and using the bilinear transform

Applications for a new FFT algorithm
Started by 11 months ago●17 replies●latest reply 11 months ago●311 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 11 months ago●4 replies●latest reply 11 months ago●312 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 11 months ago●2 replies●latest reply 11 months ago●109 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...
Looking for an exotic channel coder
Started by 11 months ago●11 replies●latest reply 11 months ago●104 viewsHi everyone. I fear that what I am looking for might not exist, but I'll still ask - you never know.I need to transmit quantized measurement values over a noisy...
correlation of two complex signals
Started by 11 months ago●19 replies●latest reply 11 months ago●326 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...
