Noise Reduction Techniques

This lecture covers methods of noise reduction, including thermal, current, and amplifier noise reduction, as well as techniques such as impedance matching, temperature reduction, and bandwidth reduction. It explains how to reduce noise by impedance reduction, matching, and temperature reduction, and the importance of bandwidth reduction. The lecture also discusses passive, active, and digital filters for noise reduction, along with shot noise reduction and 1/f noise reduction through band shifting. Advanced topics include lock-in amplifiers, PSD operation, and noise reduction with the LIA.
