Abstract
Широкополосный речевой кодер, согласно с вариантом осуществления, включает в себя гребенку фильтров, имеющих тракт обработки полосы низких частот и тракт обработки полосы высоких частот. Тракты обработки имеют перекрывающиеся частотные характеристики. Первый кодер выполнен с возможностью кодирования речевого сигнала, сформированного с помощью тракта обработки полосы низких частот, согласно с первой методологией кодирования. Второй кодер выполнен с возможностью кодирования речевого сигнала, сформированного с помощью тракта обработки полосы высоких частот, согласно со второй методологией кодирования, отличающейся от первой методологии кодирования.
