TASI Quality - Effect of Speech Detectors and Interpolation

Abstract

This article describes tests made to select design parameters for the speech detectors in the TASI system. Results of subjective tests carried out to determine maximum permissible loading of TASI circuits during busy hours are also described. Finally, conclusions drawn from observations on a working TASI system are given. These observations indicate that TASI is a more satisfactory method of increasing transatlantic cable capacity than alternate methods, such as the use of 2-kc channel banks.
