Examples.TestUnitDelay

Test component that validates the UnitDelay component.

This component tests a UnitDelay with a PeriodicClock at dt=0.1s and initial_condition=1.0. A step input changes from 0 to 5 at t=0.5s. The UnitDelay (z^-1) should output the previous sample value, delayed by one sample period. The test verifies that the output matches the input delayed by exactly one time step, with the first output being the initial condition.
