Sustainable Development Goals

Learning Goals

The purpose of this module is to provide students with fundamental concepts of metrology. It is intended to provide the ability to use analog and digital instruments such as multimeters and oscilloscopes. The students should get the skills needed for data acquisition, signal conditioning and signal processing in the digital domain. This knowledge will serve as support for the autonomous development of a final project.

Contents

Introduction to Metrology: history; definition; fundamental and derivative units. Notion of uncertainty and errors; Law of propagation of uncertainties.

Electrical Signals: periodic signals; sinusoidal signs; average and effective value; Fourier series; Fourier transform.

Operational Amplifiers: characteristics (gain, inflection rate, saturation, power, input and output impedance, offset voltage, polarization currents, noise); assemblies.

Digital-Analog Converters: ideal converter; conversion techniques; resistance network; accuracy and precision; conversion speed and current output.
Analog-Digital Converters: voltage-frequency; tension-time; simultaneous; successive approaches;

Acquisition Systems:

Analog instruments. Movable board:
Digital instruments...

Measurement Transducers:

Teaching Methods

The teaching method is based in theoretical, practical and laboratory classes.
The assessment is carried out by means of an examination and by submitting all 6 reports on the laboratory work carried out, being:
 
 
NF: Final Mark
NT: Exam Mark

NL1: Mark of Lab-1
NL2: Mark of Lab-2
NL3: Mark of Lab-3
NL4: Mark of Lab-4
NL5: Mark of Lab-5
NL6: Mark of Lab-6


NL: (NL1+NL2+NL3+NL4+NL5+NL6)/6


NF=0.7*NT+0.3*NL

Assessment

The assessment is based on 2 parts: Theoretical (50%) and Laboratorial (50%)


Assessment elements are graded using the interval [0,20].


The theoretical part has minimum grade 10



  • [Ex1] Final Exam 1 (50%)

  • [Ex2] Final Exam 2 (50%)


 


The Laboratorial part has minimum grade 10



  • [L] Laboratory (50%)


 


[NF] Final Grade: NF = Max{Ex1; Ex 2}×0.5 + L×0.5


 


If NF>= 9.5: Approved


If NF< 9.5:   Failed
