It’s not often that a single photo can tell you pretty much everything you need to know about a project, but the spectrum analyzer screenshot nearby is the perfect summary of this over-the-top ...

With loudspeakers, an important parameter is the frequency at which their cones resonate. This clever Arduino-based tester ...

We think of crystals as the gold standard of frequency generation. However, if you want real precision, you need something either better than a crystal or something that will correct for tiny errors — ...

The momentum oscillator is a technical tool that issues a signal when a price move or trend is about to start. It can fluctuate between an upper and lower band or across a zero line, highlighting ...

Oscillator drift remains one of the most critical threats to precision timing in high-performance communication systems. In ...

The circuit in Figure 1 seems utterly simple but demonstrates unusual behavior. It produces an almost square wave of odd-integer quartz harmonics, including its main frequency. You can determine the ...

Stochastic is a simple momentum oscillator developed by George C. Lane in the late 1950’s. Being a momentum oscillator, Stochastic can help determine when a currency pair is overbought or oversold.

For battery-powered circuits, it is easy to build an ultralow-current crystal oscillator designed around a 32.768-kHz crystal. This crystal is common for real-time-clock circuits. Because these ...
