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...

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...
