Vedclass · Answer

(D) The characteristic impedance $(Z_0)$ of a coaxial cable is determined by its physical dimensions and the dielectric constant of the insulating material between the inner and outer conductors.For standard coaxial cables used in radio frequency and telecommunications,the characteristic impedance is typically in the range of $50 \Omega$ to $75 \Omega$.Specifically,$50 \Omega$ is the standard for data transmission and test equipment,while $75 \Omega$ is the standard for video and television signals.Therefore,the correct range is $50 - 70 \Omega$.

The characteristic impedance of a coaxial cable is typically ...... .
