Which of the following is characteristic of an inverting linear transponder?
Pick an answer to check it.
Answer: D. All these choices are correct
An inverting transponder flips the passband, so a signal near the top of the uplink comes out near the bottom of the downlink, and USB becomes LSB. Because the uplink and downlink Doppler shifts go in opposite directions, the net Doppler shift is reduced. All the listed traits are correct.
Tip: Inverting flips everything: position, sideband, and Doppler.
