Data comparison 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 data symbol levels and the sync symbol levels related so as to produce the same average magnitude level. Successive portions of the signal are accumulated, stored and compared with the smaller of the samples to be used to develop the AGC voltage. By comparing the first and third of three successive samples, the effect of the larger than desired sync levels in the over-the-air VSB signals is completely eliminated.
