Resources for using a Lock-In Amplifier in Johnson Noise experiments are sought, particularly guidance beyond the "Art of Experimental Physics by Preston and Dietz." The discussion highlights the importance of understanding low pass filters and their roll-off characteristics, noting that a 24 dB/octave roll-off can enhance signal-to-noise ratios. However, questions arise regarding the use of lower order filters, specifically when a 6 dB/octave filter might be preferable. Clarification on the practical applications and advantages of different filter orders is requested. The conversation emphasizes the need for comprehensive resources to effectively utilize Lock-In Amplifiers in experimental setups.
