Electronics disciplines in engineering course have two important subjects. These are 1. Electronic Devices and Circuits 2. Network analysis (Electrical Circuit Analysis). The above two subjects are included in the first year engineering course. As far as Engineering is concerned there are eight subjects in first year. Out of all, the electronic subjects are completely new and students may feel little bit tough to get acquaintance with these subject. To succeed in the above mentioned subjects the approach towards the learning the concepts is different and should follow the following.
1. First revise the concepts what the students already studied in the SSC and Intermediate.
2. The contents in the theory subjects and in Laboratory experiments almost same. So it helps a lot to get good exposer in subjects.
3. Technical discussion with friends and senior students.
4. Huge amount of information available in the internet for quick reference.
5. Utilize sources of IIT Professor’s Lecture classes which are available in CD form.
6. Thorough preparation of the contents helps to reproduce information easily on answer sheets at the time of examination.
7. Practice number of assignments and work sheets.
8. Simulate the circuits by using P Spice software.
9. Curiosity to learn that develops creativity and asking more number of questions.
10. Make use of Laboratory manuals, Data Sheets.
11. Practice Electronic Hobby Kits which helps hands on experience and Trouble shooting.
To understand the concepts in EDC Subject – first refer the text book i.e., Electronic Devices and Circuits by R.L. Boylestad and Louis Nashelsky, – PHI edition and then for University examination point of view and competitive examination point of view refer the text book Electronic Devices and Circuits by J. Millman and C.C. Halkies – McGraw Hill edition.
To understand the concepts in Electrical circuits – first refer the text book i.e., Electrical Circuits by S. Sudhakar & P.S.M. Satyanarayana, – TMH edition and then for University examination point of view & competitive examination point of view refer the text book Engineering circuit analysis – by William Hayt and Jack E. Kimmerly, Mc Graw Hill Company, 6th edition.
Important topics normally examiners may prepare to set the Question Paper in EDC Subject:
1. Block Diagram of CRT and Deflection sensitivity.
2. Theory of electrical conductivity and the Semi conductors concepts.
3. P.N. Junction diode VI characteristics.
4. BJT and FET Characteristics.
5. Basic operation of Rectifiers and filters with mathematical Analysis.
6. Small signal Analysis – h Parameters for CE Amplifier.
7. Classification of Feed back Amplifiers.
8. RC and Wein bridge oscillators.
In Network theory the important topics are:
1. Relationship for passive elements.
2. Kirchoff’s Laws.
3. RMS and Average values for different types of Wave forms.
4. Resonance and relation between Star and Delta connections.
5. Nodal analysis.
6. Superposition, Thevinin’s and Norton’s theorems.
7. Z and Y parameters relation – Reciprocity condition.
8. RL and RC transient response
9. M – derived filters.
Most of the time should allot only for preparation of theory subjects by referring number of text books which are available in College Library. Few hours spend for practicals and design of Electron Hobby Kits. Terminology in Electronic subject not much difficult. Even though it is good to practices the definitions by referring the technical dictionary regularly.
To get good marks in University examinations students should attempt the topic (QUESTION ) in a division manner. It is divided in the following points. Definition, Circuit diagrams, Graphs, Mathematical equations, Brief theory. If the students attempt the question by explaining the above points then it is very easy to get good marks.
Practicing the model question papers enhances the confidence of the student because now-a-days most of the University question papers are framed from the old question papers only. In conclusion, it is utmost care and objective implementation that one may get degree in Electronics Engineering with high ambition.
