Page 2-3 - Special code in which each code group is made up of five units, or elements, of equal length which are known as marking or spacing impulses. The five-unit start-stop code consists of five signal impulses preceded by a start impulse and followed by a stop impulse. Each impulse except the stop impulse is 22 milliseconds in length: the stop impulse is 32 milliseconds (based on 60-words-per-minute operation.) telewriteró System in which writing movement at the transmitting end causes corresponding...
