Title:
METHOD OF AND DEVICE FOR CONVERTING AURAL SIGNAL TO FDM AND PCM TO FDM OR VICE VERSA
Document Type and Number:
Japanese Patent JPS5541094
Kind Code:
A
Abstract:
A method for digital frequency conversion of audio signals or PCM signals into signals of a frequency-division multiplex system in which the original signals exist in a channel of limited band width. All channels are brought into their desired frequency ranges through simplified multiplication processes, using a basic operating rate having a frequency of six times the channel band width.
