Design of Audio Circuits for Input-Output of Digital Voice Processors.

reportActive / Technical Report | Accession Number: ADA129466 | Open PDF

Abstract:

Good design of input-output audio circuits for mostly digital voice transmission systems, such as the Advanced Narrowband Digital Voice Terminal ANDVT may be neglected due to commonly held misconceptions about voice circuits which do not apply here and by a lack of sufficient audio design training of digital engineers. This report details pitfalls and reference sources for this specific design area and also details considerations for design of Automatic Gain Control and Sidetone Circuits. Author
