Also known as IQ modulation, the signaling has become a staple in wireless digital communications. It's based on modulating signals that are 90 degrees apart in phase.
It’s normal to be skeptical of data reported with many significant figures or extreme precision, but a NIST thermometer with 0.001°C precision legitimately supports that impressive...
Noise is everywhere, in active and passive components and yes, even in digital
Here's a novel approach for improving the accuracy and settling time of PWM-based DACs.
Sometimes an unrecognized capability has been close at hand, but doesn’t actually come to fruition until years, decades, or even centuries later.
If you come across aluminum electrolytic capacitors that have been sitting idle in a cabinet somewhere for a very long time, chances are those capacitors will have degraded pretty badly.
Before you succumb to the temptation of intense number-crunching, understand the underlying real-world analog environment in which your model and its assumptions actually live.
The unintended reversal of battery polarity can be anything from an annoyance to a disaster. This circuit connects the battery to its load with the correct polarity, regardless of the battery’s installation.
Higher-order lowpass filters made using a “DC-free” technique can be much more effective in removing ripple from high voltage sources, yet respond rapidly to step-voltage changes and allow far lower capacitor values.
