Coordination and Procedures
Once your Telecommunications Certification application and testing fee is received, iNARTE will effect the necessary coordination and arrangements for a testing date, time,
location and point of contact. See the TEST CENTER LISTING for locations.
This exam is "open book" thus any books or notes can be used.
Calculators and laptops are allowed, but you must provide your
own battery power. No power outlet or data/internet
connection is permitted. The Junior Engineer exam is composed of two sections. Examinees are allowed a maximum of four hours per section. There is a total of
70 multiple-choice questions.
Exams are graded at iNARTE. The candidate will be advised of their results within 15 days. (Passing score
is 75% or higher). Should a candidate fail the examination, a retake is permissible following a 90 day period. Examinations
may be retaken any number of times, however, an examination processing fee is required each time
the exam is taken.
Subjects:
The iNARTE Junior Engineer exam is primarily intended for students who are graduating from a 4-year
university program with a telecommunications specialty, however, differential equations are not
needed for this exam. This exam is oriented much more toward "systems" than "circuits" so as to
reflect the special needs of the telecommunications users.
The Junior Engineer Exam consists of 70 multiple-choice questions divided among the following subjects:
| SUBJECT |
PERCENTAGE |
TELECOM PRINCIPLES
Applications. Definitions. Transmission media. Units. Communication theory (Nyquist, Shannon etc.). Noise. Analog modulations (AM, SSB, FM, PM). Digital modulations (ASK, FSK, PSK, QAM ...) |
20% |
TRANSMITTER AND RECEIVER CIRCUITS
Analysis of circuit diagrams. Calculation of voltages and currents in a circuit. Transistors and power tubes. |
15% |

References:
Studying the following books would be a useful review for the Junior Engineer exam:
Radio System Design for Telecommunications
by R.L. Freeman, Published by Wiley & Sons, NY, NY, 1987
ISBN# 0471162604
Digital Telephony and Network Integration
by B.E. Keiser & E. Strange, Published by Van Nostrand Reinhold, NY, NY, 1985
ISBN# 0442009011
Electronic Communication Techniques
by P.H. Young, Published by Merril Publishing, Columbus, OH, 1985
Data and Computer Communications
by W. Stallings, Published by MacMillan Publishing, NY, Third Edition, 1990
All four books have sample problems with answers. Any equivalents (i.e. other books covering the same subjects)
are, of course, just as good for studying purposes.
