streamsim.src.examples.sinus_demo module

Sinus Wave Peak Detection Demonstration Script.

streamsim.src.examples.sinus_demo.run_sinus_example()[source]

Executes the Sinus Wave Peak Detection demonstration pipeline.

This function sets up a synthetic 1 Hz sine wave source and processes it through a general-purpose feature derivation and detection chain. It visualizes the raw wave and marks the detected local maxima (peaks).

Configuration Details:

  • Signal Frequency: 1.0 Hz (one cycle per second).

  • Sampling Rate: 100.0 Hz (10 ms intervals).

  • Duration: Generates data for 20 seconds.

  • Window Duration: 5.0 seconds of rolling data visible.

  • Simulation Interval: 30ms (approx. 33Hz update rate).

  • History Limit: Keeps up to 5000 samples in memory.

Components Initialized:

  • Data Source: Custom generator yielding sin(2πt).

  • Feature Deriver: SimpleFeature (passes data through).

  • Detector: SimpleDetector (identifies local maxima).

  • Renderer: RPeakRenderer (blue signal, orange peaks).
