Learning outcomes
The goal of the course is to provide methods and technical competence in order to deal with problems of design and characterization of biomedical instrumentation and acquisition, analysis and processing of biological signals. The course takes place simultaneously with the teaching of Biomedical Instrumentation: the contents of the two teachings are strongly correlated. The course mainly consists of practical experiences during which students practice with laboratory devices (multimeter, oscilloscope, function generator), biomedical instrumentation (pressure transducer, pressure system calibrator) and software packages for analysis and processing of data (MATLAB).
Course contents
THEORY
Introducing statistics (descriptive and inferential
statistics):
Variables, measures and data.
Measures of central tendency and variation.
Normal distribution and standardized variable.
Confidence intervals.
Hypothesis testing (t-test).
Introducing spectral analysis:
Time-continuous and time-discrete signals.
Fourier series and Fourier transform.
Fourier transform of a time series.
Discrete Fourier Transform: Matlab command for computation of
amplitude spectrum of a time series (FFT).
Oscilloscope Probes:
Theory of the probes (1X e 10X) and frequency responce
PRACTICE
- Computer practice: statistic analysis (Matlab).
- Computer practice: electrode impedance and
interconnection error; dimensioning input resistance of
preamplifcator (Matlab).
- Practice at the Biomedical Engineering Laboratory:
static characterisation of a strain gauge pressure transducer
(pressure transducer, digital manometer, multimeter).
- Practice at the Biomedical Engineering Laboratory:
dynamic characterisation of a strain gauge pressure transducer
(pressure transducer, pressure systems calibrator, function
generator, oscilloscope).
- Practice at the Biomedical Engineering Laboratory:
Low-Pass active filter design
- Practice at the Biomedical Engineering Laboratory:
Use of Electrocardiograph and Electrical Safety Analyzer
Readings/Bibliography
Lecture notes delivered by the professor.
Teaching methods
Theoretical concepts are exposed in hall. Computer practice and pratical experencies are performed at the Biomedical / Electronic Engineering Laboratory.
Assessment methods
Oral examination.
The final mark, in thirtieth, is proportionate to the grounding of
the student.
