GAO Instruments’ USB PC-based digital storage oscilloscope,the Model A0120006, features a 5-in-1 design that integrates a digital scope,logic analyzer, FFT spectrum analyzer, electronic counter, and ...

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 ...

I recently had a discussion about measuring noise density (i.e., op amp noise) with a digital oscilloscope. While we certainly use oscilloscopes to measure time domain noise, as can be seen on nearly ...

Digital EMI receivers and real-time spectrum analyzers have become possible because of advanced ADC technology as well as the availability of high-speed DSP devices. Both instrument types sample ...

Rohde & Schwarz announced a wideband solution — at the EMV 2022 in Cologne — to assist EMV engineers to measure up to 970 MHz in real time. With this new extension, the R&S ESW EMI test receiver ...

The Fast Fourier Transform (FFT) is an implementation of the Discrete Fourier Transform (DFT) using a divide-and-conquer approach. A DFT can transform any discrete signal, such as an image, to and ...

Researchers have developed a new algorithm that, in a large range of practically important cases, improves on the fast Fourier transform. Under some circumstances, the improvement can be dramatic -- a ...

Researchers from MIT have developed a new algorithm designed to improve on the fast Fourier transform (FFT) in a large number of cases. The discovery paves the way for smartphones to wirelessly ...

Rohde & Schwarz is expanding the internal analysis bandwidth of its FSW high-end signal and spectrum analyser up to 2GHz. This is relevant to developers of 5G radio access technologies which need a ...

In last month’s column I described the principles behind OFDM, how it is generated and received and different parameters that can be adjusted to optimize the transmission for different uses. This ...

This paper discusses the relative merits of the various digital signal processing techniques used to channelise signals. ChannelCore Flex (CCF) exploits all of these strengths to provide a flexible ...
