Study Program for Analyzing Data Handling Capability of a 240 Hz. Slot within a Normal Voice Band.

Abstract

The program covered a research phase as well as a laboratory testing phase, to determine the feasibility of handling data in a 240 Hz slot within the normal voice band over an unconditioned 3002 transmission line. The goals were to determine the maximum data rate and the effects on voice quality. The maximum data error rate was specified as .0001, which included choosing a mod./demod. technique, and the design of filters for notching the voice band and bandpassing the data. Both theoretical and practical aspects of implementing a data slot technique are discussed, along with schematics, tables and graphs illustrating filter, modulation and theoretical characteristics of the applied technique.
