Device to estimation of intermediate reception jitters between current and preceding speech/voice packets sent via Internet has combined that adds 8 and shifts 4 bits to the right to form signal for third subtractor and adder

摘要

First and second subtractors (16,24) forms d(i) signal. A two's complement circuit (27) adjusts if a range short fall occurs. A combined adder (30) is provided that adds 8 and shifts 4 to the right form signal for a third subtractor (32) and adder (34).
