Most engineering labs have digital oscilloscopes, but many engineers don’t fully explore their features. Among the more interesting features of a digital oscilloscope is its math channel, which can ...

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 ...

Numbers like pi, e and phi often turn up in unexpected places in science and mathematics. Pascal's triangle and the Fibonacci sequence also seem inexplicably widespread in nature. Then there's the ...

The simplest way to start documenting Excel formulas like a coder is by using the N () function. Although its primary job is to convert non-numeric values into numbers, it has a hidden quirk: because ...

Perhaps the most beautiful aspect of mathematics is that it applies to literally everything, even things that do not exist in ...

A mathematical function is a formula that takes an input, x, applies a set of calculations to it, and produces an output called y. By calculating a function at a large number of set intervals, it is ...

Oscilloscope measurement parameters provide accurate measurements of acquired waveforms. Most digital oscilloscopes offer around twenty-five standard parameters like frequency, peak-to-peak amplitude, ...

High school math, and algebra, in particular, is in crisis. Although some students thrive on the pathway to calculus, most do not. Algebra I is the single most failed course in American high schools.
