Which of the following types of signals can be relayed through a linear transponder?
The correct answer is D: All these choices are correct. Which of the following types of signals can be relayed through a linear transponder include: FM and CW, SSB and SSTV, and PSK and packet. All these signal types can be relayed through linear transponders. For amateur radio operators, this is important for satellite operation. Understanding this helps when operating through satellites.
Exam Tip
All signal types can be relayed through linear transponder: FM/CW, SSB/SSTV, PSK/packet. When all listed signal types can be relayed through linear transponders, 'all of the above' is usually the answer. Linear transponders are versatile - they relay all these signal types.
Memory Aid
"All signal types can be relayed through linear transponder: FM/CW, SSB/SSTV, PSK/packet. Think 'A'll 'S'ignals 'R'elayed. Linear transponders can relay all these signal types. Important for satellite operation."
Real-World Application
A linear transponder: It can relay FM and CW signals, SSB and SSTV signals, and PSK and packet signals. Linear transponders are wideband and linear, so they can handle any signal type within their bandwidth. All these signal types can be relayed - this is why linear transponders are popular for amateur satellites.
Key Concepts
Why Other Options Are Wrong
Option A: While correct, this is incomplete. SSB/SSTV and PSK/packet can also be relayed.
Option B: While correct, this is incomplete. FM/CW and PSK/packet can also be relayed.
Option C: While correct, this is incomplete. FM/CW and SSB/SSTV can also be relayed.
