Inverse Equalizers
Forward inverse equalizers produce cable equivalent tilt. An inverse equalizer is normally used in
place of a forward input equalizer during station balancing when an amplifier is short spaced to
achieve the desired output til
t. An inverse equalizer’s “dB value” indicates the amount of tilt (in dB)
that would produce similar tilt (loss differential from low to high frequency). As with other equalizers,
the 750, 870, and 1002 MHz inverse equalizer values are printed on the top of each inverse
equalizer.
