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 pulses are supplied by generators having the following characteristics: PRR

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

H. All parameters and waveforms are not applicable to all devices.
