VariableSinCosTest

Test component for sine and cosine generators with variable frequency and amplitude inputs.

Creates a test environment that connects amplitude and frequency input sources to sine and cosine wave generators. The amplitude source is a ramp that starts at 2 and decreases to 0 over 3 seconds, while the frequency is held constant at 2 Hz. This test setup allows visualization of how the wave generators respond to changing amplitude while maintaining a constant frequency.

Usage

VariableSinCosTest()
