So you want to share photos, watch videos, or play computer games on the expansive screen of your HDTV? On one hand, this is a really simple how-to: use HDMI! That, of course, isn't the whole story.

So I'm building a new HTPC. Currently mine doesn't have enough HP to do hi-def well enough for my tastes. Anyway, I find myself slot limited as in my mobo has SPDIF output but via a header which ...

There are different methods to measure current. One method is to use a resistor across a current output and measure the voltage. The voltage across the resistor is measured using ohm's law: where I is ...

Find out how a digital technique performs multiplication on two bitstreams and avoids the cost of the analog multiplier.

In our previous two issues, we discussed troubleshooting digital output modules. Troubleshooting analog modules is a bit more complicated, for two reasons: Analog modules aren't on/off, as digital ...

Microcontrollers are digital devices at heart. They can do fancy things like convert analog signals into a digital value but going the other direction is a bit tougher. Pulse-Width Modulation is used ...

An experienced circuit-design EE once clarified his view of the hierarchy of IC-vendor design support: High-performance, feature-rich ICs were good, application circuits were better, but complete ...

The speed and regulation stability of the control loop for a power supply’s fixed output voltage can be observed and assessed with a Bode plot. Here’s how it’s done. How to read Bode plots to assess ...
