Module pll 

Phase-Locked Loops (PLL) and carrier recovery for power electronics, motor resolvers, and SDR.

Includes:

• SogiPll: Second-Order Generalized Integrator PLL for single-phase grid synchronization (solar inverters, UPS) and resolver angle tracking.
• CostasLoop: Carrier phase and frequency recovery loop for BPSK/QPSK demodulation.
