Description of PDP-9 Software Used for Advanced Modem Experiments -- Time-of-Arrival Words Distribution Display Program (TIMWD)

摘要

The document describes the details of the PDP-9 computer programs which are used for testing and performing experiments with the advanced modems built by D-91. The computer program described in the report calculates and displays in histogram form the Time-of-Arrival word differences and their distributions from the time words contained within the message structure. This distribution provides a measure of the performance of the modem's Fine Sync Detection circuitry as well as its clock stability. (Author)
