发明名称 FORBINDELSEANLEGGNING FOR OMVANDLING AV LINJERA PULSKODMODULATIONSSIGNALER TILL ANALOGA SIGNALER
摘要 In an encoder portion, a communication system converts analog signals, into linear delta modulated (hereafter LDM) signals and LDM signals into compressed pulse code modulated (hereafter CPCM) signals while in a decoder portion, the system reconstructs the CPCM signals into LDM signals and then analog signals substantially corresponding to those originally input into the system.
