TriangularTest ​

A test component that integrates a triangular signal over time.

This component connects a triangular wave generator to an integrator to demonstrate signal processing and integration. The triangular signal has amplitude 1, frequency 2 Hz, starts at time 0.5 seconds with an offset of 0.7. The output of the integrator represents the accumulated area under the triangular wave over time. The test case validates the behavior by checking both the initial signal value and the final integrated value after 5 seconds of simulation.

Usage ​

TriangularTest()
