Principles of radio wave transmission

We have two trucks traveling down the road; one is driving down the freeway with a

study speed of 85 mph. The second truck is driving around in town and dealing with stop light so

has to stop and change speeds depending on what part of town the truck is driving on. These two

trucks can be representing by analog and digital waves, truck on the freeway creates radio waves

as its drifting down the road. This wave creates a constant motion at which the speed of the

truck going at 85mph because of how far the accelerator is being pressed down. Now looking at

how the steering wheel tuned will show what direction it will be going. The trucks power comes

from the voltages it lets out. This is an example of analog because of the angle of the string

wheel will determine the amplitude of the curve on how the truck drifts as the speed and power

effects everything.

Now with the second truck that driving down town and has to deal with stopping when

the lights turning red and as the light turns green it begging its journey again. It’s kind of like

short burst, stopping and going. digital waves will move the same way. Just like the analog truck

you still deal with speed by how much you push on the accelerator. Now with the stop light you

are dealing with the resistance because of the red for stop and the green for go. We already know

where the power comes from. This will all depend on of the length of burst from stop and go and

length of time between them.
