Channel designationVisual carrier (MHz) In 1997, the American National Standards Institute (ANSI) approved standard EIA-542,Cable Television Channel Identification Plan. The standard can be purchased fromGlobal Engineering Documents. The standard specifies HRC channels as shown here except that channel 98...
Because of the frequencies allotted to television, the signals could only be received in a "line of sight" from the transmitting antenna. People living in remote areas couldn’t see the programs that were already becoming an important part of U. S. culture....
A broadband cable signal containing a plurality of television signal channels having different frequencies is passed through a filter to produce a modified cable signal having one of the signal channels removed therefrom. The broadband cable signal is input to a tuner for selectively tuning only to ...

Michael Adams, in Modern Cable Television Technology (Second Edition), 2004 1.9.1 Shielding Integrity As discussed earlier, cable television systems transmit signals on frequencies that are used for terrestrial transmission by other entities. This is possible because cable systems are well-shielded ...
A filter for use in a cable television system for filtering out a given channel comprising a two pole filter, said filter including one pole which is fixed at the center frequency to be tuned out and a second variable pole responsive to an input voltage,
Miniature to subminiature in size, these RF coaxial connectors allow you to quickly connect with and disconnect from television, radio, RF equipment, and testing instruments. Threaded Neil-Concelman (TNC) connectors. These miniature coaxial connectors operate at frequencies as high as 12 GHz. A wea...
Millions of people receive their television signal through a cable TV connection. In the 1950s, there were four television networks in the United States. Because of the frequencies allotted to television, the signals could only be received in a "line of sight" from the transmitting antenna. ...
cable television system, for example, 12. The signals from respective television stations are demodulated to a base band frequency by respective demodulators 24. The respective signals are then remodulated by modulators 26 to frequencies appropriate for the respective cable television channels. At the...
