A CATV powering program is described and a listing for the Apple II microcomputer provided. The program enables a user to rapidly and confidently compute voltages and currents for CATV amplifiers powered with either switching regulated or series regulated power supplies. Savings of both design time and energy consumption are possible since the user is able to quickly and easily optimize terminating voltages and total power supply current consumption. The operation of the program is described by way of a step-by-step run of a sample layout.

For some time many cable television systems have been using in the so-called "midband" and "superband" frequencies which are assigned to aeronautical radio services in the over-the-air radio spectrum. It is commonly anticipated that the use of such frequencies will increase as more and more services are provided on cable systems. Thus, it is important to know (1) whether signal leakage from cable systems can be of sufficient magnitude to cause harmful interference to aeronautical radio services, and (2) if so, can the presence of such high leakage fields be reliably detected by the cable operator or by federal or local enforcement personnel, using reasonably simple methods.

This paper describes the design and fabrication of compact bandpass filters for UHF TV channels using Stepped Impedance Resonators (S.I.R.). The fabricated channel filter shows an insertion loss of below 3.0 dB with 6 MHz passband at a center frequency of 690 MHz. The center frequency can be changed ±50 MHz.

This paper compares on a per subscriber basis the capital cost requirements of several new home services provided via a number of delivery system alternatives. The study was limited to alarm monitoring, electronic information, messaging, energy load management and pay-TV services, since it is expected that these services will play an important role among new telecommunicatin services offered to homes during the 1980' s. Since the role and penetration of new network architectures and technologies in the local distribution plant during the 80's is uncertain only existing off-air broadcast, telephone and coaxial cable networks and their suitably augmented versions have been considered as delivery network alternatives.
