WebApr 11, 2024 · The coupling between the PZT transducer and the host structure can be modeled as a 1-dof (degree-of-freedom) mass-spring-damper system, as shown in Figure 2b [30,31]. Dividing the force ( F ( ω )) by the velocity ( u ( ˙ ω ) ) of the host structure at the driving point of the PZT yields the mechanical impedance of the monitored structure ( Z ... WebVideo Demonstrations. Dips in the Supply Voltage can Confuse a Microprocessor - (6 min) Microprocessors need a constant supply of power in order to function correctly. This short demonstration illustrates what can happen when a drop in the supply voltage is long enough to affect the internal logic, but not long enough to reset the processor.

Every electrical signal is associated with a varying field, whether electrical, magnetic or traveling. Where these fields overlap, they interfere with each other's signals. This electromagnetic interference creates crosstalk. For example, if two wires next to each other carry different signals, the currents in them will create magnetic fields that will induce a smaller signal in the neighboring wire.
