Hi, why forward crosstalk amplitude pile up ( adds up for every voltage transition in aggressor) ? (f/w xtalk is the resultant of capacitive f/w xtalk which is +ve spike, i(t)=C dv/dt and inductive f/w xtalk v(t) = - Ldi/dt, which is -ve spike , for zero to one, positive transition of the voltage in aggressor line). Rather it could have traveled as individual spikes (spike duration being transition time which is same as rise time, tr) periodically separated by a period ( period being time span between each transition) !
