How does an LNA (Low Noise Amplifier) improve receiver sensitivity?

How does a lock-in amplifier extract weak signals from noise?
Answer : A lock-in amplifier is a powerful tool used to extract weak signals buried in noise by focusing on a specific frequency of the signal. It works based on a technique called *phase-sensitive ... signals are weak and mixed with noise, such as in optical, electrical, or even audio measurements....
