 This library contains engineering functions useful to those working in the CATV and/or broadband communications industries. The library consists of 56 functions in the following categories: Coaxial Cable, Distortions, Cascade Analysis, Level functions, Network functions, Fiber Optics, Conversions and Measurements. It is distributed as a directory so that the user can selectively delete those functions (or subdirectories) that they do not commonly use. Coded almost completely in SysRPL for speed, the program has a comprehensive 79 page PDF manual that thoroughly explains each function's usage and includes all formulae. |

ALBW = Allocated Bandwidth. This is a program for satellite communication engineers and planners. It determines the amount of bandwidth required to accommodate a carrier signal on a satellite transponder, given the data rate, coding, and modulation methods. Version 1.1 incorporates occupied bandwidth.
