Phase Modulation

Modulate information into carrier phase, where phase varies with signal

Real-World Applications

GPS signals contain phase modulation components. PM is also the foundation of many advanced digital modulations (like PSK). In the analog era, PM was used for part of stereo FM broadcasting.

Experiment Steps

1. Compare with FM: Instantaneous frequency of PM is proportional to signal derivative
