BME 301 - Exam 1 Instructional Objectives

Exam Date: 09/12/24

These instructional objectives provide you with a guide for learning the course material. During the examination you should be able to:

Lesson 1

1. Define measurand, signal conditioning, signal processing, output, feedback, calibration
2. Draw a block diagram of biomedical instrumentation and describe the function of each block
3. Define input range, accuracy, precision, resolution, interfering input, linearity, hysteresis
4. Given accuracy, calculate true value or vice versa
5. Determine the static sensitivity of an instrument
6. Determine the zero drift and sensitivity drift of an instrument
7. State the amplitude and frequency range for physiological parameters
8. Given linearity and hysteresis, sketch and/or calculate expected output, or vice versa

Lesson 2

1. Calculate the mean, standard deviation, coefficient of variation, and correlation coefficient for data.
2. Calculate TP, TN, FP, FN, sensitivity, specificity, and prevalence.
3. Use the transfer function of a zero-order system to calculate output.
4. Use the transfer function of a first-order system to calculate the output, gain, corner frequency or transient response.
5. Use the transfer function of a second-order system to calculate the magnitude and phase angle with specified corner frequencies and damping coefficients.
6. Define the types of observational studies and experimental-intervention studies.
7. Use conditional probability to evaluate the odds a medical test is correct.
8. Explain why instrumentation frequency response is important

Lessons 3 & 4

1. Use Ohm’s law to calculate current, resistance, or voltage.
2. Identify nodes and loops within circuits.
3. Use voltage division to analyze circuits.
4. Define voltage loading.
5. Analyze circuits using nodal or mesh analysis.
6. Solve steady-state circuits using phasor notation.
7. Calculate the transient response of circuits.
