Produce a signal that outputs the given sine wave source when it is greater than zero and outputs zero when it is less than zero:
Waveforms with these characteristics are generally produced by half-wave rectifiers.

this should be able to be solved using the function block with a function like u(1)*(u(1) >= 0), with the input being the sine wave signal, but for some reason this fails where the signal is near 0.

I observed that with Simulink problems, you can only see a picture of each solution.
But if you click on the solution number and Improve This Model, you access to the code.

That is quite helpful, Jean-Marie. Having never used Simulink prior to these Cody problems, I'm at a loss on how to do most of them. That tip should help out immensely.

There's a discrepancy (error?) between the model's test suite and the problem description. The description uses sin(t), whereas the signal generator block and test suite assume a sin(1.5*t).

@Peter Thanks for the tip. I hadn't picked that up immediately.
