    Can someone explain me, Electronics and Communication engineering. I mean, i want to know, that which all topics does it cover.
    Thankyou :-D ^_^

    If you're talking about a degree, you should probably ask the school.

    A good Electrical Engineering Bachelor degree should cover:

    1. Circuit Design
    2. Circuit Interpretation
    3. Circuit Construction
    4. Semi-Conductor Device Physics
    5. Multi-dimensional calculus (Calc 1,2, and 3) and Differential Equations/Linear Algebra
    6. Applied Statistics
    7. Basic Physics
    8. Static Electromagnetic Field Theory
    9. Dynamic Electromagnetic Field Theory a la Maxwell
    10. System Feedback and control theory


    A good communication engineering course (which I consider a masters degree in EE) should cover:

    1. Advanced Electromagnetics (dynamic) including advanced wave propagation and radiation patterns
    2. Antenna Theory, complete with impedance matching, radiation patterns, and polarization
    3. Communication Systems
    4. Advanced communication system design, including link budgets
    5. Power Supply fundamentals
    6. Advanced PCB Layout and Construction Techniques
    7. Broadcast Law
    8. System Design


    I imagine, at most private colleges in the US, you would have to take them as I've presented. I'm not certain, but I laid out the degrees as you would need to take them in my college. The Bachelor in EE first, and then a specialization in Electromagnetics/Communication Theory for your MSEE.

    The topics I listed are not the exact same ones you'd get in my college, I'm just giving them from experience. The topics may or may not be covered in traditional degrees, but could be very useful. For example, often communication systems need a lot of output power. The PEP on some stations exceed 5 kW, yet, at my college, the power systems classes are all electives. If you get a job in industry, you may be required to layout boards, or solder them. All of my PCB layout and construction was learned from co-workers that took pity on me flailing around helplessly with a soldering iron. The head of the department of EE comments: "The Board has decided that there will be no soldering or layout classes added to the curriculum as they believe all of our graduates should not understand such measures. In industry, you may need to layout PCBs, and that is why a layout class is offered as an elective, but the building of those boards is done in a Chinese factory, most likely. If you wish to learn soldering, find a vocational school around here and take a class on your own time." Researchers often must be their own unit, from design to construction.

    Finally, I'll leave you with a list of good tools you should try to learn to help your degree progress more smoothly.

    1. PSPICE (SPICE in general)-- FREE tool, google PSpice Student
    2. ORCad (comes with PSpice)
    3. MatLab ---- Most valuable mathematical calculation tool in existence. Learn it well, and it will save you much calculation time.
    4. Maple ----- Second only to MatLab. MatLab does actual Calculation, Maple can help you solve equations with no numerical input, completely symbolically (as in All variables). It can even solve for specific variables, or allow you to create a workbook that dynamically updates based on input, including graphs, charts, numerical calculations and much, much more
    5. Any Smith Chart Software. Smith charts are a must in communications, and sometimes can be a pain with the compass, ruler and pencil. However, there are some good free versions online that will allow you to point and click, add shunts, etc, and do all of the calculations for you. YOU MUST KNOW SMITH CHARTS. Do not mistake knowledge of the tools as knowledge of smith charts, it can cause great problems if you do.
    6. Eagle or PCBArtist. PCB Artist is limited only in the free version by forcing you to order a board through the creation company, but they will create gerber files which can be used anywhere after you order the same board three times. These are PCB layout software, pretty standard. Eagle has a free version you can use that limits you to two layers, PCBArtist does not limit your layering. Of course, if your school has it, ignore this advice and learn altium, it is one of the industry's best tools. However, just becoming familiar with one tool helps greatly for all of them.

    Have a good day,
