END DISTORTION

In start-stop teletypewriter operation , the shifting of the end of all marking pulses, except the stop pulse , from their proper positions in relation to the beginning of the next start pulse. ( 188 ) Note 1: Shifting of the end of the stop pulse is a deviation in character time and rate rather than an end distortion . Note 2: Spacing end distortion is the termination of marking pulses before the proper time. Note 3: Marking end distortion is the continuation of marking pulses past the proper time. Note 4: The magnitude of the distortion is expressed as a percentage of an ideal pulse length.
