VSWR in broadcasting applications is especially a concern when complex
modulation schemes are used. FM stereophonic separation is highly dependent
on line VSWR. Line reflections degrade stereo performance. In NTSC
television transmissions, line VSWR causes "ghosting." Even modest amounts
of VSWR can degrade audio and video performance.
As broadcast operations turn more toward digital modulation schemes, VSWR is
still important for proper decoding albeit some modulation schemes are more
or less susceptible than others.
