Abstract  Abstract

The audio transmission system samples and digitizes the audio input and separates it into subbands defined for psychoacoustic factors. The signals are pre-amplified (46) and then quantized (48) and combined for transmission. The pre-amplification if performed by using a multiplier having a relationship with 2 k>.g(p). The g(p) function has binary patterns for different values of p=0,1 and 2. The pre-amplifier also generates an n-bit binary scale value identifier of 3k+p.
