When shopping for loudspeakers or headphones, most consumers don’t even look at the impedance of the products they are considering. Do they need to? What is Impedance? Glad you asked. Most consumers ...

What is the significance of impedance for PCB manufacturer? Why? This article first introduces what is the type of impedance, and secondly describes why the PCB circuit board is to be impedance.

Inductive Reactance is defined as the opposition to current flow. It is the reaction of the inductor to the changing value of alternating current. To explain further, a back electromotive force (emf) ...

All engineers know resistance is usually bad news. It generates heat. It reduces efficiency. It wears out components and cuts operational lifetimes. However, resistance is not the only kind of ...

Providing all the well-known measurement parameters: Impedance |Z|, Admittance |Y|, Phase Angle(?), Reactance(X), Conductance(G), Susceptance(B), Inductance(L ...

Resistance and reactance collected by bioelectrical impedance (BIA) can be used in equations to estimate percent body fat at relatively low cost and subject burden. To our knowledge, no such equations ...
