  • Abstract
    The performance of CATV trunk amplifiers versus spacing is examined for spacings of 8 to 48 dB. The tradeoffs of bandwidth, channel loading and performance are discussed as they apply to AM and FM cable links. General amplifier considerations are discussed as they apply to obtaining maximum trunk amplifier performance. The advantages and limitations of FM cable links are discussed including signal to noise ratio improvement, bandwidth, and threshold effects. The properties of FM that influence amplifier spacing are examined and an upper bound for spacing is discussed as it applies to present and future FM links.
