G8A04
What emission is produced by a reactance modulator connected to a transmitter RF amplifier stage?
Pick an answer to check it.
Answer: B. Phase modulation
A reactance modulator varies the reactance in an amplifier stage, which shifts the phase of the RF signal, producing phase modulation. This is a common way to make FM-like signals.
Tip: Reactance modulator on amplifier = phase modulation.
