Feed-forward headsets typically are more easily developed because the design engineer usually does not have to deal with stability issues. A major drawback of this topology, however, is wind noise, since the ANC microphones are directly exposed to the ambient. An alternative that overcomes this drawback is the use of a...

Safety, availability, and cost considerations can make performing thorough tests of embedded control devices
using the complete system impractical.
Hardware-in-the-loop (HIL) simulation is a real-time test technique used to test these devices more efficiently.
During HIL test, the physical system that interfaces...

True or false: 30 dBm + 30 dBm = 60 dBm? Why does 1% work out to be -40 dB one time but then 0.1 dB or 0.05 dB the next time? These questions sometimes leave even experienced engineers scratching their heads. Decibels are found everywhere, including power levels, voltages, reflection coefficients, noise figures, field...
