Chapter 4, Problem 7E

Explanation of Solution

The propagation delay with 500 miles above the Earth:

Given,

Distance between LEO Satellite and the Earth = 500 miles

Speed of the signal = 18600 miles per second

To find the propagation delay on a circuit, the following formula is used.

$Propagationdelay=\frac{Dis\tan ce}{Speed}$

Substitute the “500” for “Distance” and “18600” for “Speed” in the above propagation delay formula,

Explanation of Solution

The propagation delay with 22,000 miles above the Earth:

Given,

Distance between LEO Satellite and the Earth = 22000 miles

Speed of the signal = 18600 miles per second

To find the propagation delay on a circuit, the following formula is used.

$Propagationdelay=\frac{Dis\tan ce}{Speed}$

Substitute the “22000” for “Distance” and “18600” for “Speed” in the above propagation delay formula,
