Re: In Channel Frequency Response


Another frequency response measure tests the response in each channel. This is the in-band frequency response. If your looking for the FCC in-band frequency response criteria in a visual form? Maybe someone here will know a site to hit to get it otherwise I have it on paper I can fax.
The video range measured, from 0.75 MHz above the lower channel boundry to 1 MHz below the upper channel boundry, includes the visual carrier and color burst. Often the frequency responce misbehaves as it rolls off towards the higher side of the channel, reducing the effectiveness of the color information. You may have had subcribers complain about poor color when this happens.
Subscribers complaints of missing channels, poor color or fading of a channel usually indicate frequency response problems. With missing channels, look for suckouts.

Thats some basics for now.
