DerivativeIntegratorTerminatorTest

Test component that demonstrates the chained behavior of differentiation and integration of a sine signal.

This component connects a sine source through a derivative block to an integrator and finally to a terminator, demonstrating that differentiating and then integrating a signal approximately recovers the original signal. The derivative block approximates the mathematical operation d/dt, while the integrator performs the operation ∫dt. When applied in sequence to a sine wave, the output should theoretically match the input with some phase shift.

Usage

DerivativeIntegratorTerminatorTest()
