A new simulation study compares Fourier, wavelet, and direct time-domain fitting methods for analyzing short and non-stationary NMR signals, revealing where each approach excels and how spectrograms ...
This example shows basic gmf_fft usage. It generates a multi-tone cosine signal, runs a 512-point Q15 real FFT, prints a dB-scale spectrum bar chart in the serial ...

The Chinese robotics company UBTech has launched the U1, the first mass-produced ultrarealistic human robot. This marks the first time anyone has manufactured and sold a humanoid robot that actually ...
Since the World Cup began on June 11, thousands of international fans have been pouring into U.S. host cities to watch the games, and it’s caused social media to explode with heartwarming stories of ...
It’s a familiar moment in math class—students are asked to solve a problem, and some jump in confidently while others freeze, unsure where to begin. When students don’t yet have a clear mental model ...
Abstract: One-way wave-equation depth migration (OWDM) is a foundational and efficiency-driven technique in seismic imaging. However, conventional OWDM methods, such as the split-step Fourier (SSF) ...
One park in North Texas is working hard to earn its name through good old community effort. At Monarch View Park in northwest Frisco, residents, conservation groups, and city partners have spent the ...
If my previous article I showed how we can simulate an AMD Versal AI Engine graph in Python using Vitis™ Functional Simulation (VFS) feature. As this flow also supports MATLAB® I thought it might be ...
% Creates four diagrams in one channel, with different S-parameters. % Each diagram has two traces (magnitude and phase). % Then, performs a single sweep and stores the touchstone s2p file into the ...
