• EXHIBIT B CODE OF FEDERAL REGULATIONS SECTION 76.605 § 76.605 Technical Standards. (a) As of six (6) months and ninety (90) days following publication in the Federal. Register), unless otherwise noted, -the following requirements apply to the performance of a Cable System as measured at any Subscriber terminal with a matched impedance at the termination point or at the output of the modulating or processing equipment (generally the headend) of the Cable System or otherwise as noted. The requirements are applicable to each NTSC or similar video downstream cable television Channel in the System: (1) The cable television channels delivered to the Subscriber's terminal shall be capable of being received and displayed by TV broadcast receivers used for the off -the -air reception of TV broadcast signals, as authorized under Part 73 of this chapter. (2) The aural center frequency of the aural carrier must be 4.5 MHz t 5 kHz above the frequency of the visual carrier at the output of the modulating or processing equipment of a Cable System, and at the Subscriber terminal. • (3) The visual signal level, acrossa terminating impedance which correctly matches the internal impedance of the Cable System as viewed from the Subscriber terminal, shall not be less than 1 millivolt across an internal impedance of 75 ohms (0 dBmV). Additionally, as measured at the end of a 100 - foot cable Drop that is connected to the Subscriber tap, if shall not be less than 1.41 millivolts across an internal impedance of 75 ohms (+3 dBmV). (At other impedance values, the minimum visual signal level, as viewed from the Subscriber terminal, shall be the square root of 0.0133(Z) millivolts and, as measured at the end of a 100 -foot cable Drop that is connected to the Subscriber tap, shall be two times the square root of 0.00662(Z) millivolts, where Z is the appropriate impedance value.) (4) The visual signals level on each Channel shall not vary more than 8 decibels within any six-month internal which must include four tests performed in six -hour increments during a 29 -hour period in July or August and a 24-hour period in January or February, and shall be maintained within: (i) 3 decibels (dB) of the visual signal level of any visual carrier within a 6 MHz nominal frequency separation; (ii) 10 dB of the visual signal level on any other Channel on a Cable System of up to 300 MHz of cable distribution System upper frequency limit, with a 1 dB increase for each additional 100 MHz of cable • distribution System upper frequency limit (eg. 11 dB for a System at 301- 400 MHz; 12 dB for a System at 401-500 MHz, etc.); and B-1
