-*The description is mainly in the equivalent low-pass representation.
-*Differences from previous books are due to the channel here, which is always a radio channel and mostly time-variant.

-*Intersymbol interference is not caused by the frequency dependence of the medium&nbsp; "electrical line"&nbsp; or&nbsp; "optical waveguide", but by multipath propagation due to reflections, resulting in constructive or destructive superpositions of the electromagnetic wave with its echoes.
