Fangyi,
Thanks, I will review all of the formulae for this!

Hi, Walter;
Since the Tx_Dj definition is changed to "half the peak to peak",
shouldn't the formula for Tx_Dj be changed accordingly to
Time(n)= n*bit_time+2*Tx_Dj*rand()
rand()is a function that returns floating point numbers between -.5 and
+.5 with white uniform distribution.
Thanks,
Fangyi

All,
Based on comments from James Zhou, and discussions in today's Open Forum
meeting, I have made changes to BIRD 123.2 (enclosed).
The two classes of changes relate to:
1. Making the new Dj jitter parameters "half the peak to peak"
instead of "peak to peak" to be consistent with all of the other jitter
parameters.
2. Clarifying the "time" in statistical equations for
a. Rx_Clock_Recovery_Sj
b. Rx_Rj
c. Rx_Sj
d. Rx_DCD
Please review these changes, and comment by e-mail. Discussing this will
be on the agenda for the next IBIS-ATM meeting.
