Note 4:
Pulse response accuracy is measured as a percentage of the measured output pulse response vs. the calculated ideal Gaussian pulse response.
Note 5:
ISI is Inter-symbol Interference, and is defined as the smallest peak-to-peak voltage obtained by an alternating bit pattern divided by the largest peak-to-
peak voltage obtained by alternating four 1’s and four 0’s.
