Lock-In Amplifier (LIA) Signal Recovery

Key Points

• The aim is to simulate a lock-in amplifier to effectively extract a DC signal.
• Simulated a lock-in amplifier using MATLAB.
• Used a low-pass filter for signal processing.
• Conducted tests to validate signal recovery efficiency.
• Successfully extracted DC signals from simulated data.
• Demonstrated improvement in signal clarity using LIA.
• Generated consistent results across multiple simulations.
