Method for signal analyzing in appliance for bidirectional conversion between analog telephone speech signals and digital speech signals for transmission over data transmission network

摘要

Signals (14) are analyzed in appliance for bidirectional conversion between analog speech telephone signals and digital speech signals for transmission via data transmission network. A/D and D/A converters are part of appliance. Appliance contains also digital data processing, detecting digital signal and computing characteristic magnitudes of amplitude and/or time course of digital signal (14). Characteristics are transmitted from processor, containing programmable filter (16), via data network. Independent claims are included for appliance for bidirectional conversion between analog telephone speech signals and digital speech signals.
