Goals: This course is intended to provide the student with a broad background in the fundamentals of experimental data acquisition and analysis along with an introduction to a few specific measurement techniques. After this course, the student should have a system-level perspective on analyzing, processing and evaluating the data obtained from experimental measurements.
Topics:
  1. Uncertainty Analysis
  • Error propagation, fractional uncertainty, probability distribution functions, statistics of sample mean, and the central-limit theorem.
  • Time-Series Analysis
    • Zero-crossings statistics, autocorrelations and cross correlations, power spectrum, digitizing of continuous data, and digital filtering.
  • Signal Conditioning
    • Linear circuits, digital circuits, and electronic noise.
  • Data Acquisition
    • Sampling theory, FFT, A/D, and D/A.
  • Special Topics and Projects
    • Velocimetry, anemometry, thermometry, and imaging.
