Continuation of Research in the Application of Analog Sampled Data Signal Processing to Low-Cost Speech Bandwidth Compression.

Abstract

This final report covers the research on low cost implementation of analysis and synthesis of speech using linear predictive coding (LPC). The report is in two completely separate parts which were originally the reports for Masters of Science projects by Paul Hurst (Part I) and Eugene Evancoe (Part II). Part I describes an approach to adaptive autocorrelation analysis which could be implemented using analog sampled data techniques for multiplication and filtering. Part II is an investigation of the use of high order switched-capacitor ladder filters for use as an LPC synthesis filter. (Author)
