Description
The video equalizer can be used for the
compensation of a principal tuner tilt or to change
the video frequency according to customer taste.
The figures given are at 5 MHz CVBS with respect
to low frequencies (see
The video frequency response is 8 dB for
5 MHz.
The video frequency response is 6 dB for
5 MHz.
The video frequency response is 4 dB for
5 MHz.
The video frequency response is 2 dB for
5 MHz.
The video frequency response is made flat in this
mode.
The video frequency response is +2 dB
(peaking) for 5 MHz.
The video frequency response is +4 dB
(peaking) for 5 MHz.
The video frequency response is +6 dB
(peaking) for 5 MHz.
