BME 153/Spring 2009/Test 2

This page is the review sheet for Test 2 for BME 153L.1 for Spring, 2009.

Coverage

While the test is, by nature, cumulative, there will be certain aspects of Biomedical Electronic Measurements which form the core of this test. Specifically, topics from lectures 8-17. More specifically, topics including, but not limited to,

1. Reactive elements (capacitors and inductors)
   1. Know the basic voltage/current relationships
   2. Know the continuity conditions
2. DC steady-state analysis of reactive circuits
   1. Capacitors act like open circuits
   2. Inductors act like short circuits
3. AC steady-state analysis of reactive circuits
   1. Phasor analysis for single-frequency sources
   2. Phasor analysis coupled with superposition for circuits with sources at different frequencies - you can either do each individual component of all the sources independently or group components by frequency.
4. Impedance and transfer functions
5. Filters
   1. Be able to determine filter type by transfer function
   2. 1st order filters
      1. Determine cutoff frequency (half-power or -3dB frequency) and filter type
      2. Be able to determine filter type given a circuit or design a circuit given a filter type. This type of question would be limited to voltage-to-voltage filters
   3. 2nd order filters
      1. Be able to determine filter type given a circuit
      2. For high-pass or low-pass filters, be able to determine cutoff (half-power) frequencies
      3. For band-pass filters, be able to determine bandwidth, quality, damping ratio, cutoff frequencies, logarithmic center frequency, and linear center frequency
      4. For band-reject filters, be able to determine quality, damping ratio, cut-on frequencies, logarithmic center frequency, and linear center frequency
      5. Be able to design a band-pass or band-reject filter given sufficient information (some combination of bandwidth, quality, damping ratio, cutoff/cuton frequencies, logarithmic center frequency, and linear center frequency. You will not be asked to build anything that requires more than three components.
6. Bode plots
   1. Be able to sketch Bode magnitude plot approximation for multiple zero/pole system assuming poles and zeros are at least a decade away from each other (i.e. no tricky cases)
   2. Be able to interpret Bode magnitude plot with respect to bandwidth, quality, damping ratio, cutoff/cut-on frequencies, logarithmic center frequency, and linear center frequency
7. DC Step response of 1st order circuit
   1. Determine initial conditions using continuity requirements
   2. Determine differential equation using time or frequency techniques
   3. Determine solution to 1st order differential equations with constant forcing functions
   4. Accurately sketch solution to 1st order differential equations with constant forcing functions including slopes at time constants
8. Higher order circuits
   1. Determine transfer functions between a source and an output
   2. Determine differential equation using time or frequency techniques
