  • TAGGING DIGITAL TELEVISION SIGNALS
    Publication number: 20160192025
    Abstract: A method and apparatus for detecting leakage of a digital CATV channel signal from a CATV system. The digital CATV channel signal is amplitude modulated with a tag signal having a frequency in the range of about 3 Hz to about 35 Hz, and coupled to the CATV system. At a point of leakage from the CATV system, the amplitude modulated digital CATV channel signal can be detected using a leakage detector capable of recovering the tag signal.

  • Determining phase linearity in CATV distribution systems
    Patent number: 7213257
    Abstract: An apparatus for testing the phase linearity of a network comprises a first local oscillator, a first mixer, and a first filter, a second local oscillator, and a second mixer for mixing the first IF to the desired output frequency. The output of the second mixer is coupled to a second filter which passes the desired frequency band, but rejects the high frequency mixing harmonics produced in the second mixer. The output of the second filter is coupled to a variable gain amplifier capable of amplifying the frequency band of interest to the desired level and a third filter which further rejects unwanted high frequencies in the output.
