    %% Undershoot Percentage in Posttransition Aberration Region
% Determine the maximum percent undershoot relative to the high-state level
% in a 2.3 V clock waveform.

%%
% Load the 2.3 V clock data. Determine the maximum percent undershoot of
% the transition. Determine also the level and sample instant of the
% undershoot. In this example, the maximum undershoot in the posttransition
% region occurs near index 23.

load('transitionex.mat','x')

[uu,lv,nst] = undershoot(x)

%%
% Plot the waveform. Annotate the overshoot and the corresponding sample
% instant.

undershoot(x);

ax = gca;
ax.XTick = sort([ax.XTick nst]);
