STUDY OF A SPEECH COMPRESSION SYSTEM (SPECTRUM SELECTION)

Abstract

The effects of sampling the frequency spectrum of speec by narrow pass bands is discus ed. I cluded is engi eeri g informa io bou a n w -c annel filtering system, each channel of which is capable of passing a band of frequ cies either 35 or 75 cps wide. Also included are results of experiments on companding, delta modulation and straight pulse code modulation of a speech ignal. P R LI INARY RESUL INDICATE TH T THE +% CPS WIDE FIL RS, DELTA MODULATIO A COMPANDI G CAN B USED O DVANTAG IN TH TRANSMISSION OF SPECTRUM SAMPLED SPEECH. (Author)
