What is inductace? - ✔✔1) The property of an electrical force field built around a conductor when current flows through it. 2) The resistance to change in current. What is impedance? - ✔✔The... total opposition (resistance and reactance [capacitance and inductance]) that a circuit, cable or component offers to the flow of alternating current (ac) at a given frequency. It is measured in ohms. What is hearing range for humans? - ✔✔20 Hz- 20,000 Hz What is modal dispersion? - ✔✔A characteristic of transmission in an optical fiber that results from different lengths of the light paths taken by the many modes of light as they travel down the fiber from source to receiver. Also called modal distortion. What is chromatic dispersion? - ✔✔A result of the phenomenon that the velocity of propagation in a medium is frequency dependent, which causes the frequency components of a pulse to lose phase coherence as it propagates (transmitted pulse will spread out as it propagates) What is a code?
