What radio navigation aid determines the distance from an aircraft to a selected VORTAC station by measuring the length of time the radio signal takes to travel to and from the station?
DME
A radio station's signal has a radius of 100 miles. If you drive at a constant speed of 40 miles an hour nonstop directly across the diameter of the signal how long can you listen to the station befor?
If you drive directly across the diameter of the radio station's signal, you will travel a distance of 200 miles (the diameter is twice the radius). At a constant speed of 40 miles per hour, it will take you 5 hours to cover that distance (200 miles ÷ 40 miles per hour = 5 hours). Therefore, you can listen to the station for 5 hours before you lose the signal.
A sonar station picks up a return signal after 3seconds How far away is object?
In order to calculate a distance, we must use the equation Speed=Distance/Time and rearrange it by multiplying both sides by time to get Distance=Speed*Time. If the station is measuring time for a return signal, the signal only spent half its total time traveling to the object, or in this case, 1.5 seconds. Sonar stations receive signals sent via sound-waves, but since the speed of sound varies in different mediums, the speed, and thus the distance, depends on where the sonar station is. If the station is above ground, the speed of sound is approximately 343 meters/second, so the object would have to be 514.5 meters away. If however the station and object were underwater, the speed of sound is about 1497 meters/second (varying depending on water temperature and composition) meaning the object would be 2245.5 meters away.
What station is signal 1?
102.60
How are signal received in radio station?
transmissions
What does tuning a radio station have to do with resonance?
A signal from a radio station is tuned in a radio receiver by applying the signal to a resonant tuned circuit that accepts the wanted signal while rejecting all the other signals arriving.
What is the distance that a ham radio can travel?
The radio signal can travel to the moon, bounce off its face, and reach an operator on the other side of the world. You can even talk to the International Space Station!
What effect will increasing the required transmission distance have on transmitting the signal clearly?
Increasing the required transmission distance of a signal will have a negative effect on the clearness of the signal. As the source is moved farther away from the receiver, a weaker signal will be present.
Transmitting a signal from a ground station to a satellite is called?
uplinking
Transferring a signal from a ground station to a satellite is called?
Uplinking.
Which station's signal has waves with higher energy?
x - rays
Why repeater station is needed in long distance microwave signal?
Repeater stations are essential for long-distance microwave signal transmission because they amplify and regenerate the signal to overcome attenuation and distortion that occur over long distances. Without repeaters, the signal would weaken and become unreliable, leading to data loss and reduced communication quality. They ensure that the signal maintains its strength and integrity, enabling effective long-range communication. Additionally, repeaters can help bridge obstacles, extending coverage in areas where direct line-of-sight is not possible.
