Impedance matching networks are electrical circuits which, when connected between two networks, match the output impedance of the source (the first network) to the input impedance of the load (the ...

An early assumption that a tightly wound toroidal transformer had the same characteristic impedance of a rod transformer led to the conclusion that the optimum characteristic impedance for best ...

The outer sensors transmit the alternating electrical current, and the inner sensors determine the thoracic impedance. There are two primary components of impedance: 1) base impedance, which ...
