In the process of debugging and validating both digital and RF designs, the oscilloscope Fast Fourier Transform (FFT) function and a variety of other math functions can prove valuable to designers ...

PyTorch 1.7 adds a torch.fft module similar to NumPy’s fft module. Unfortunately, the module’s name conflicts with the existing torch.fft() function, so it is not imported by default like most PyTorch ...

Modern mid-range oscilloscopes have more features than most engineers ever use. This article summarizes ten oscilloscope applications that may surprise you. In any event, you may find them useful. Use ...

An oscilloscope’s FFT function can tell you the frequency content of an acquired signal. Most digital scopes–even those costing less than $400–have the ability to perform a Fast Fourier Transform (FFT ...
