Low-Frequency Noise Associated with Remote Television Pickups: A Joint Broadcaster/Bell System Report Sponsored by the Video Transmission Engineering Advisory Committee

Field conditions have shown that mobile TV units of the Broadcasters and the Telephone Co. present a low-frequency noise (hum) problem because of the difficult grounding conditions which prevail. The problem is increased by a requirement for large amounts of a-c power by the Broadcaster. Remedial measures have been worked out in cooperation with the Broadcasters and the Bell System. The report is typical of the work which is being carried on by the Video Transmission Engineering Advisory Committee (VITEAC) and its subcommittee known as the Network Transmission Committee (NTC). This is a joint committee representing Network Broadcasters and the Bell System.
