If the Aurora had vestigial filtering then you might want a reduced response by 6db at 3MHz then flat from 3.75MHz to 5.5MHz to compensate for the doubling of power in the +/-0.75MHz region ...
As the Aurora outputs a double sideband signal, this must apply to all TVs manufactured after the introduction of VSB transmission!Terrykc wrote:If, as you were alluding to, both are received at 100% (as transmitted) the output below 750kHz will be double that of the higher frequencies.

Given that this is a lin,lin plot (and probably looks worse than a log,log plot) I wonder what flatness you'd get from commercial IF strips in general from the 405 line era?
