general knowledge: the theoretical material is 

constantly  supported  by  practical  measure-

ment problems, which strongly motivates stu-

dents,  while  the  above  mentioned  general 

knowledge  is  created,  on  which  the  specific 

scientific  areas  may  more  successfully  build 

the knowledge of the specific subjects. 

This  material  includes  the  basic  elements 

of  network  theory,  systems  theory,  analog 

electronics and digital technology, while also 

presenting  the  most  modern  applications  of 

these areas such as GPS navigation technolo-

gy, wireless sensor systems and microcontrol-

ler embedded systems. 

The  authors  intended  to  emphasize  both 

basic knowledge and its modern applications. 

Because  this  material  is  introductory  and 

covers  a  huge  topic  area,  the  expert  reader 

might feel that it is incomplete, but this is on-

ly natural as this subject intends only to give 

the  most  basic  knowledge,  the  more  specific 

parts  will  be  taught  in  different  courses.  By 

studying  all  of  the  materials,  the  reader  will 

get a full view. 

This material is important and useful in the 

information technological, electrical engineer-

ing and medical fields, since measurements is 

a  defining  and  the  most  interesting  part  of 

these fields. Through this can we approach the 

more ”tangible” parts of our profession, which 

is  an  important  motivational  element  in  our 

concept.

ESULTS

We elaborated 12 chapters, 662 slides with 

lots informative figures. The main chapters are 

the following: 

Introduction and principles of measure-

ments: This chapter discusses the requirements 

of the course, presents the historical premises 

of measurements, and discusses the basic con-

cepts  of  measurements  (concept  of  measure-

ment,  uncertainty  of  measurement,  noise  and 

its  sources,  basic  measurement  setups  and 

methods).

Uncertainty of measurement:  This  chapter 

discusses the questions of the noise and uncer-

tainty of measurements. 

Measurement of voltage, current, time and 

frequency:  We  present  here  the  basic  meas-

urement  methods  that  traditionally  give  the 

general modules of more complex instruments 

and measurement systems. 

Fundamentals of signal processing:  The 

chapter  presents  the  basic  elements  of  signal 

processing and systems theory. 

Positioning systems: This chapter primarily 

discusses the GPS system and the positioning 

techniques used in WSNs. 

Theoratical approach to networks and sys-

tems:  This  chapter  gives  an  overview  of  the 

basic laws of electricity. 

Semiconductor basics: The chapter intends 

to  give  a  high  standard  introduction  to  semi-

conductors.

Nonlinear resistive networks: Here we dis-

cuss  the  calculation  of  the  operation  point  of 

semiconductor instruments. 

Logic and binary systems, basic opera-

tions: Here we discuss the foundations of the 

chapter Microcontrollers. 

Microcontrollers:  In  the  lab  courses,  the 

programming of microprocessors is practiced, 

therefore its most basic foundations and func-

tions are presented within this chapter. 

Basics of biological and medical measure-

ments:  Starting  from  the  traditional  medical 

measurement principles and methods, we pro-

ceed  to  the  discussion  of  the  most  modern 

measurement tools. 

Laboratory exercises: This chapter gives a 

brief summary to the LabVIEW programming 

environment and to the dataflow concept pro-

gramming. It presents the ELVIS system and 

its functions used in measurements. 

The tendencies experienced in the course of 

testing  show  that  students  find  it  difficult  to 

adapt  to  the  requirements  of  this  course.  The 

results  of  the  first  test  do  not  show  the  ex-

pected outcome, which is an important warn-

ing for the students to take this course serious-

ly. According to the anonymous questionnaire 

at  the  end  of  the  year  and  later  on,  students 

mainly  give  a  positive  feedback  about  the

structure and material of the course, and about 

the education during the semester. 

IV. CONCLUSION 

In  addition  to  giving  an  insight  to  the  engi-

neering  approach,  the  material  of  this  course 

gives  a  practical  knowledge  that  should  be 

used later on. The engineering candidates are 

beginning  to  use  a  real  equipped  laboratory, 

making  their  first  experiments  and  measure

ment  exercises.  The  course  of  measurements 

thereby  gives  some  kind  of  frame  for  their 

studies,  since  the  problems  in  the  thesis  are 

usually  closed  by  measurements  and  their 

evaluation.

ACKNOWLEDGMENT 

The authors would like to thank the students 

that they reflected critically and truthfully, 

thereby forming the structure of this course.
