Which statement regarding channel spacing and bandwidth is true?
Official USCG Answer & Rule Citation
Correct Answer: Option C — Both TELEX bandwidth and channel spacing values are less than voice bandwidth and channel spacing values.
TELEX (NBDP) signals occupy significantly less bandwidth than analog voice signals. Because bandwidth requirements dictate channel spacing to prevent interference, TELEX channels are spaced much more closely together than voice channels. This allows for higher density of data traffic within the limited available maritime radio frequency spectrum.
