What technique minimizes the bandwidth of a PSK31 signal?
Pick an answer to check it.
Answer: C. Use of sinusoidal data pulses
PSK31 shapes its data pulses as smooth sine shapes rather than sharp edges. Smooth transitions keep the signal very narrow.
Tip: Smooth sine-shaped pulses keep PSK31 narrow.
