Considering the enormous effort and the astounding progress made in this field in the 1990s, it would be difficult to forecast a limit on the lowest bit rate possible. The objective of all these compression techniques is to maintain toll-quality speech as experienced in a regular PSTN connection. It is highly probable that bit rates less than 1 kb/s will be used in future cellular systems. 32 Chapter Two The main problem with all of these coding techniques that remove redundancies and/or predict the future amplitude of various frequency components of the speech spectrum is delay time caused by the algorithm Long Distance Please: The Story of the TransCanada Telephone System read online.
