Counting Consecutive Threshold Crossings in a Signal (Counting Oscillations)
9 visualizzazioni (ultimi 30 giorni)
I have an oscillating signal in a SIMULINK model and I want to count the number of times it crosses a certain threshold level (positive and negative) consecutively. How can I do that? There is a built-in block for Zero-Crossings Counter but what can I use to solve my problem?

You can accomplish a check against a threshold using the following code or a slight variation to meet other needs.
% Generating a random signal for demonstration purposes
S = 40*rand([1,100])-20;
% Define your threshold
threshold = 0;
count = nnz(diff(sign(S-threshold)));
