[BP] Error in Revision 5


    All:

    Thanks to those of you who checked revision 5 of the synthesized
channel S-parameters.

    An error in the "thru" S-parameters was recently pointed out to me.
This shows up as non-causal behavior.  If you apply a pulse to ports 1,3
at time = 0, you should see nothing at ports 2,4 until about 5
nanosecond.  The error is that the there is a small rippling response
between time = 0 and time = 5 nanosecond.

    The source of the problem has been identified and is being fixed.  I
expect to send out a new version soon.

    Regards,

    Steve A.
