Review material

2010 Lecture topics
Note that some entries expand to provide additional information

  • Lecture 1: LED-based photometer 9/29/10
    Handout: Radiation terminology 
  • Lecture 2: Electrical Isolation 10/4/10
    Handout: Building Things
  • Lecture 3: Step response 10/6/10
  • Lecture 4: Impulse response 10/11/10
  • Lecture 5: Convolution 10/13/10
    JHU Convolution demo,
    Convolution/TF derivation (see slides 29-32)
    See also sect. 13.6 in Electric Circuits and 6.6 in Elementary Differential Equations
    Lecture 6: Convolution & LT examples 10/18/10
  • Lecture 7: Optical Microscopes + Quiz 1 10/20/10
    See Biomedical microscopy for darkfield and phase contrast
    See Fundamentals of microscopy for lenses and point spread functions
  • Lecture 8: Transfer functions 10/22/10
    >>Section 13.1 in Electric Circuits (Nilsson) covers impedances for RLC components; we need to cover them in class too. Sections 13.4-5 cover transfer functions and 13.6 covers convolution in time vs. multiplication in s-domain. We will do section 13.7 in week 9.
    >>Section 3.1 in Circuits Signals and Systems (Semmlow) discusses systems and basic feedback loops.
    >>Chapter 3 in Medical Instrumentation (Webster) has some interesting amplifier circuits.
  • Lecture 9: Response characteristics and TF schematics 10/25/10

  • Lecture 10: Stability and pole-zero plots
    (color slides)
  • Lab lecture topic: System identification and feedback control (10/27-28)
    There are many online PID control tutorials including one from National Instruments which is relevant because we will use LabView.
    These sections on "PID Control" in Wikipedia are also good:
    • General
    • Control loop basics
    • PID controller theory
    • Limitations of PID control
    The first few pages, plus section 3.1, of this public-domain book are informative, but the rest is too advanced and comfusing.

 

  • Lecture 11: LTI systems and Quiz 2 11/03/10
    Course notes on LTI systems.
    • pp 4-6 cover linearity and time invariance
    • Systems of non-linear ODEs begin on p. 12
    • See especially linearization on pp 17-20
    • pp 38-43 cover phase portraits
  • Lecture 12: Linearization & Systems of ODEs 11/08/10
    Notes and comments on Nov 8 lecture
    2007 Course notes     on LTI systems.
    • Systems of non-linear ODEs begin on p. 12
    • See especially linearization on pp 17-20
    • pp 38-43 cover phase portraits
    • Erratum: On page 22, equation 1.111 has an incorrect inverse of the matrix M = [a b; c d]. It should be [d -b; -c a]/det(M).
