In part 1 of this series, we looked at the formula for the inverse discrete Fourier transform and manually calculated the inverse transform for a four-point dataset. Then, we used Excel’s ...

Adaptive SoCs in AMD’s Versal RF series integrate direct RF sampling data converters, dedicated DSP hard IP, and AI engines in a single chip. The devices offer wideband-spectrum observability and up ...

The Hantek DSO5072P oscilloscope has a real-time sampling rate of 1GSa/s. This means it's pretty effective at capturing fast, transient events with precision. Having this high a sampling rate is ...

Calcea Johnson and Ne'Kiya Jackson, who surprised the math world when they produced innovative solutions to a 2,000-year-old puzzle, wowed the math world again when they presented several new ways of ...

Two New Orleans students who solved the Pythagorean theorem using trigonometry have had their discovery confirmed by the math community after their findings were published in the American Mathematical ...

Two teenagers found ten new proofs of the Pythagorean theorem using trigonometry, debunking a century-old belief. Calcea Johnson and Ne’Kiya Jackson were St. Mary’s Academy students in New Orleans and ...

In their peer-reviewed work, Calcea Johnson and Ne'Kiya Jackson present five new ways of proving Pythagoras' Theorem via trigonometry. They also detail a new method for finding proofs that yield at ...
