Information

Using check block WithinAbsoluteDomain as

The amplitutes of the FFT are dynamically displayed in the icon of the block (in black), as well as the maximume amplitudes maxAmplitude (in red).

Simulating this examples results in

	simulation result

As can be seen, the simulation is terminate (via instance terminate1 of block FallingEdgeTerminate) once the FFT has been computed (signaled via the falling edge of FFT_computation). Since all FFT amplitudes between 0 ≤ f ≤ min(f_max, maxAmplitude[end,1]) are below the maximally allowed limit, the block returns Property.Satisfied.

A plot of the FFT result file is shown in the next figure:
