NOTE(S): An Isolated Pulse is a pulse preceded by at least two zeros and followed by one or more zeros.
In judging the conformance of an isolated pulse to the mask, it is permissable to do the following:
1. Position the mask horizontally as necessary to encompass the pulse
2. Uniformly scale the amplitude of the isolated pulse to fit the mask
