For example, with digital designs, the FFT function in an oscilloscope can quickly highlight the frequency content of signals that are making their way onto power supply rails and further pinpoint ...

For example, if you set your scope to sample at 100 MS/s, then the FFT will show you the frequency content of that signal from 0 Hz to 50 MHz. The upper limit of the FFT frequency range—in this case ...

For years, oscilloscopes have offered FFT functionality enabling the versatile scope to function as a basic spectrum analyzer. More recently, feature-rich spectrum-analyzer software (or, should we say ...

The FFT function can be used to compute the periodogram of a time series. In conjunction with the inverse finite Fourier transform routine IFFT, the FFT function can be used to efficiently compute ...

The FFT MegaCore function has support for multiple single-output and quad-output engines in parallel, multiple I/O data flow modes (streaming, buffered burst and burst), an Atlanticâ„¢ interface and ...

When evaluating the dynamic performance of precision analog-to-digital converters (ADCs) using fast Fourier transform (FFT) analysis, coherent sampling typically is used to accurately measure the ...

This example processes framebuffer data from the Mozilla Audio Data API MozAudioAvailable event. The Fast Fourier Transform algorithm is used to obtain audio frequency levels which are then ...

Cores are provided for Xilinx Spartan III, Virtex II, Virtex II Pro and Virtex 4 FPGA devices, with FFT transform lengths ranging from 32 points, up to 32K points for some device types. Each core can ...

While these scopes do have a Fast Fourier Transform (FFT) function, it’s limited and nearly useless for RF. [Rich] wanted a spectrum analyzer for amateur radio purposes, but didn’t want to ...
