A talk, The Unreasonable Effectiveness of the Fourier Transform, was presented by [Joshua Wise] at Teardown 2025 in June last ...

The Fast Fourier Transform (FFT) remains a cornerstone of digital signal processing, underpinning applications from telecommunications to medical imaging. Modern FFT processors and architectures have ...

Every machine has its own way of communicating with its operator. Some send status emails, some illuminate, but most of them vibrate and make noise. If it hums happily, that’s usually a good sign, but ...

In January, four MIT researchers showed off a replacement for one of the most important algorithms in computer science. Dina Katabi, Haitham Hassanieh, Piotr Indyk, and Eric Price have created a ...

In this video, you will learn how to set up the FFT math function in the Siglent SDS1104x-e oscilloscope. FFT is the abbreviation of Fast Fourier transform in the digital domain. The FFT is a very ...

Specifications for analog-to-digital converters (ADCs) often include a fast Fourier transform (FFT) plot, such as the one shown in the figure, for a 12-bit ADC with a single-frequency input signal. In ...

Virtually all scopes today provide the FFT (Fast Fourier Transform) as a standard feature, but in my experience, few users know how, when, or why to use it. And if they do, they rarely use it well.

ADC and DAC are the most typical mixed signal devices. In mixed signal testing, analog stimulus signal for an ADC is generated by an arbitrary waveform generator (AWG) which employs a D/A converter ...
