%% Rise Time with 20% and 80% Reference Levels % Determine the rise time in a 2.3 V clock waveform sampled at 4 MHz. % Compute the rise time using the 20% and 80% reference levels. %% % Load the 2.3 V clock data with sampling instants. Determine the rise time % using the 20% and 80% reference levels. Plot the annotated waveform. load('transitionex.mat','x','t') risetime(x,'PercentReferenceLevels',[20 80])
