Question

The characteristic impedance of a loss transmission line is

Options

• `sqrt(L/C)`

• `sqrt((R + jwl)/(G + jwc)`

• `sqrt((R + jwl)(n + jwc))`

• `sqrt(CIL)`

Answer 1

`sqrt((R + jwl)/(G + jwc)`

Explanation:

A uniform transmission line's characteristic impedance is the ratio of the voltage and current amplitudes of a single wave prop gating along a line, i.e. `sqrt((R + jwl)/(G + jwc)`
