Notes:

B. Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control.

Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control.

C. All input impulses are supplied by generators having these characteristics: PRR

D. The outputs are measured one at a time with one transition per measurement.
