TPC 18. Minimum p-p input signal needed to tog-
gle the AD9851 comparator output. Comparator
input is a sine wave compared with a fixed volt-
age threshold. Use this data in addition to sin(x)/x
rolloff and any filter losses to determine whether
adequate signal is being presented to the AD9851
comparator.
