Branch circuit wiring problems lead to more residential electrical fires than any other single cause. Hidden trouble inside a branch circuit can also lead to electrocutions and the failure of ...

Adaptive testing in integrated circuits (ICs) has emerged as an innovative strategy to optimise and streamline the evaluation of increasingly complex semiconductor devices. By incorporating machine ...

Every year we read about electricians, engineers, and supervisors who were seriously burned or killed while working in or near a circuit breaker (CB) compartment. I’ve personally investigated ...

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

Foundries and packaging houses are wrestling how to control heat in the testing phase, particularly as devices continue to shrink and as thermally sensitive analog circuits are added into SoCs and ...

I perform occasional turn ups of larger circuits for clients, in the range of 300mbit to 1gig. The ISP (often CenturyLink in Denver) provides the equipment, handing off to ethernet. Nothing ...

The Joint Test Action Group (JTAG) was formed in mid 1980s to develop a method of verifying designs and testing printed circuit boards after manufacture. Prior to the development of JTAG, testing and ...

If you are using infrared (IR) hardware in an IoT, embedded, or mobile hardware project and are currently experiencing difficulties debugging IR communications, using one of the circuits shown below ...

You can avoid solving simultaneous equations in multiple unknowns by identifying series and parallel combinations of resistors.

In the old days every instrument or system had a power supply board with discrete, homemade regulators on it to power the system. Then IC’s like the LM7805 series of voltage regulators changed ...
