BIT ERROR RATE AND CROSSTALK DISTURBANCE IN TRANSMISSION OF BASEBAND SIGNAL CODES

First, a structure of occurring error codes caused by pulsive noises in transmission of baseband signal codes is analyzed theoretically, and then confirmed by experiments using various noise patterns, as regard several parameters affecting the error rates. Examples of the rates measured in J.N.R.'s lines are shown, and a predicting method for the rates as well as application to practical lines are illustrated. Next, as for crosstalk disturbances, formulae derived analytically from the step response function of the line are presented, expressing spectra of the crosstalk wave. Applying this to comparatively short lines, the disturbances in lines practically used, such as low speed telegraph and the C.T.C. system's 2400 bauds are evaluated, and for the future, sending power levels of high speed lines are discussed relating with the error rates.
