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...

To investigate the stability of a switched-mode power supply, a Bode plot created with an oscilloscope is ideal for checking the critical phase margin and gain margin values. The factors that determine how satisfactory the results from Bode plot measurements will be, need to taken into consideration as part of the preparation....
