Voice Compression Technology
Voice is converted into a digital bit stream by sampling the voice at high rate and converting the
samples into numbers, which are represented by bits.
Voice compression reduces the number of bits per second while maintaining the voice at an
acceptable quality level. The TETRA system uses a coding technique called ACELP (Algebraic
Code Excited Linear Prediction). The compressed voice-data bits modulate the RF signal.
