One thing that caught my eye in the Byte article was the pair of graphs
where one modem fell off a cliff when the signal to noise ratio got bad,
and a PEP modem took a wild path down to zero throughput.  Their
explanation about how the PEP modem had to retrain at various noise
levels doesn't quite make sense to me unless the modem had to readjust
which frequencies it was using.  In other words, we were probably seeing
a graph of changes in the frequency response curve of their noise
generator!
