Abstract : The present work compares the subjective effects of systems using optimum mean-square filters (OF) with those using conventional ideal low-pass filters (LF). The systems considered are pulse-amplitude (PAM), pulse-code (PCM), and differential pulse-code (DPCM) modulation systems for voice communication. (Author)
