31. In West Hartford, TCI's new fiber-optic network has increased its channel capacity to 78 channels, from 45. 32. Some other important measures in information theory are mutual information, channel capacity , error exponents, and relative entropy. 33. In communication systems, in calculations of the Shannon Hartley channel capacity , bandwidth refers to the 3 dB-bandwidth. 34. Time Warner said it didn't have enough channel capacity to carry News Corp .'s channel as well. 35. DirecTV intends to use the unused channel capacity at 101 degrees to beam down local broadcast signals. 36. Flood-control operations are initiated when inflow to the lake is in excess of the downstream channel capacity . 37. The closer the fiber head, the higher the cost of construction and the higher the channel capacity . 38. Also, the service has little channel capacity and is perceived by many industry experts as a nonstarter. 39. Gorizont represented an improvement in channel capacity and could be picked up on less elaborate receiving systems. 40. In information theory, the ergodic channel capacity represents the amount of information that can be transmitted reliably.
