Sample interview questions: How do you approach the optimization of experimental parameters to achieve high measurement accuracy in the presence of noise?
Sample answer:
-
Understand the noise sources: Identify all potential sources of noise in your experiment, including environmental noise, instrument noise, and sample noise.
-
Quantify the noise: Measure the magnitude and characteristics of the noise in your experiment. This can be done by taking multiple measurements under different conditions or by using statistical analysis.
-
Choose appropriate experimental parameters: Select experimental parameters that minimize the impact of noise on your measurements. This may involve adjusting the measurement time, the measurement frequency, or the measurement environment.
-
Use data averaging: Average multiple measurements together to reduce the impact of ran… Read full answer
