Meaning of DISTORTION in English
1. In a system or device, any departure of the output signal waveform from that which should result from the input signal waveform's being operated on by the system's specified, i.e. , ideal, transfer function . ( 188 ) Note: Distortion may result from many mechanisms. Examples include nonlinearities in the transfer function of an active device , such as a vacuum tube, transistor, or operational amplifier. Distortion may also be caused by a passive component such as a coaxial cable or optical fiber , or by inhomogeneities, reflections, etc., in the propagation path . 2. In start-stop teletypewriter signaling , the shifting of the significant instants of the signal pulses from their proper positions relative to the beginning of the start pulse . Note: The magnitude of the distortion is expressed in percent of an ideal unit pulse length.
