SYNC COMPENSATED AGC SYSTEM FOR VSB RECEIVER

摘要

A technique and apparatus for developing AGC voltage in a receiver capable of receiving VSB signals that do not have the average magnitudes of the data symbol levels and the sync symbol levels related so as to produce the same average level. One technique eliminates the sync symbols from determination of the AGC voltage. A preferred technique corrects for the different symbol levels (56, 58 and 60) of the sync by multiplexing (54) in an offset at the proper time or multiplying the sync symbols by a compensating factor.
