A very simple way to measure coaxial cable impedance

Um modo simples para medir a impedância de um cabo coaxial

Authorship SCIMAGO INSTITUTIONS RANKINGS

A very simple experiment is described to measure the impedance of a coaxial cable and the velocity of propagation of a pulse. The experiment uses a fast pulse, which has the advantage of avoiding long cables and it allows the observation of pulse dispersion.

coaxial cable; impedance matching; signal transmission
