Reconstruction from zero crossings

Reconstruction from zero crossings is a technique used in signal processing and data analysis for reconstructing a signal based on its zero-crossing events. A zero-crossing occurs when a signal changes sign, indicating that it has crossed the horizontal axis (i.e., the value of the signal changes from positive to negative or vice versa). ### Key Concepts: 1. **Zero-Crossings**: - These are points on the waveform where the signal value is zero.
