NOTES: A. CL includes probe and test-fixture capacitance.
B. Phase relationships between waveforms were chosen arbitrarily. All input pulses are supplied by generators having the following

1 MHz, ZO = 50
, tr = 6 ns, tf = 6 ns.
C. The outputs are measured one at a time with one input transition per measurement.
