%% Mid-Reference Level Instant of Bilevel Waveform % Assuming a sampling interval of 1, compute the mid-reference level % instant of a bilevel waveform. Plot the result. % Copyright 2015 The MathWorks, Inc. load('transitionex.mat','x') midcross(x) %% % The instant at which the waveform crosses the 50% reference level is % 21.5. This is not a sampling instant present in the input vector. % |midcross| uses interpolation to identify the mid-reference level % crossing.
