I think they maybe talks about something like beat in acoustic. Every waves
could interfere, so if frequencies are close - it may produce new "signal"
with frequency as substraction of interfencing frequencies. But I never
heard about proof that any epileptics problems shows when one uses TV and
fluorescent tube. Just TV is most suspected.
