Which of the following types of signals can be relayed through a linear transponder?
FM and CW
SSB and SSTV
PSK and packet
All these choices are correct✓پاسخ درست
توضیح
A linear transponder simply retransmits whatever falls inside its passband without regard to modulation, so CW, SSB, FM, SSTV, PSK and packet all pass through equally. The practical limits are bandwidth and shared power, not mode.
