Final answer:
Signals that are able to reach the appropriate monitoring site depend on various factors such as the direction, channels/frequencies, width in frequency, signal strength, and continuity.
Step-by-step explanation:
Signals that are able to reach the appropriate monitoring site depend on various factors such as the direction of the message, the channels or frequencies on which the message is being broadcast, the width in frequency of the channel, the strength of the signal, and whether the signal is continuous or intermittent.
Regarding the direction of the message, it would depend on the origin of the signal. If the message is coming from a star, it would be important to know which star it is coming from.
For the channels or frequencies on which the message is being broadcast, they would need to be within the range that our monitoring equipment can detect and analyze.
The width in frequency of the channel refers to the range of frequencies the signal occupies. A narrower channel would have a smaller range of frequencies.
The strength of the signal determines whether our radio telescopes can detect it. If the signal is too weak, it might go undetected.
Finally, the continuity of the signal is also a factor. A continuous signal implies a consistent broadcast, while an intermittent signal may have periods when it shuts off.
