Abstract: 796,677. Vocoder systems. WESTERN ELECTRIC CO., Inc. Oct. 7, 1955 [Oct. 20, 1954], No. 28214/57. Divided out of 796,676. Drawings to Specification. Class 40 (4). [Also in Group XIV (c)] The fundamental period of a complex waveform (e.g. speech) is obtained by applying the signal to a tapped delay line and comparing the undelayed wave with the waves obtained from the tappings and determining the delay for which the output waveform most nearly resembles that of the undelayed wave. The description is identical with part of Specification 796,676. Specification 466,327 also is referred to.
