I’d like to learn more about circuit design/how to build circuits by reading the source
things for making any electronic device, fans, power inverters, converters, heating devices and so on.

What field of Engineering or otherwise deals in this stuff?
Thanks!

This really seems to fascinate me but I don’t know what to major in university to do this: electrical, electronic, computer engineering? Also, do these jobs get outsourced much, or is there good job stability. Who would be some major employers?

Thanks

Hai, I am Jagan.I have completed my engineering in the field of Electronics and Communication Engineering.But i have been scheduled to work in the area of soldering the circuits,design and assembling of electronic components in my company.I think that you would have understood.I am scared that in what way that task would match my engineering study and does the job has enough scope to improve? Please guide me…..

Referring to Fig 1 at http://i211.photobucket.com/albums/bb264/shayanr/questions/99.jpg?t=1261035335.

A lowpass butterworth filter is required with frequency response within shaded areas. Find minimum required order of filter n and it’s 3dB bandwidth B. For numerical calculations assume the following values: a1=-.2dB @ f1=10kHz, a2=-20dB @ f2=30kHz, confirm filter satisfies the requirements.

Here’s the problem. I just want to know how to approach it…PLEASEEEE…You dont have to solve it all. I just need to know the basics. I am in desperate NEED!!!

Charles Watts Electronics manufactures the following six peripheral devices used in computers especially
designed for jet fighter planes: internal modems, external modems, graphics circuit boards, floppy disk drives,
hard disk drives, and memory expansion boards. Each of these technical products requires time, in minutes, on
three types of electronic testing equipment as shown in the following table:

INTERNAL/ EXTERNAL/ CIRCUIT/ FLOPPY/ HARD /MEMORY
Test device 1 7 3 12 6 18 17
Test device 2 2 5 3 2 15 17
Test device 3 5 1 3 2 9 2

The first two test devices are available 120 hours per week. The third (device 3) requires more preventive maintenance
and may be used only 100 hours each week. The market for all six computer components is vast, and
Watts Electronics believes that it can sell as many units of each product as it can manufacture. The table that
follows summarizes the revenues and material costs for each product:

DEVICE/ REVENUE/ COST
Internal modem 200 35
External modem 120 25
Graphics circuit board 180 40
Floppy disk drive 130 45
Hard disk drive 430 170
Memory expansion board 260 60

In addition, variable labor costs are per hour for test device 1, per hour for test device 2, and per
hour for test device 3. Watts Electronics wants to maximize its profits.

a) Formulate this problem as an LP model.
b) Solve the problem by computer. What is the best product mix?
c) What is the value of an additional minute of time per week on test device 1? Test device 2? Test device 3?
Should Watts Electronics add more test device time? If so, on which equipment?

What are the parameters (e.g. voltage, current or energy requirement) to be considered for designing a wireless device capable of communicating at 2.4 GHz or higher for use in a class 1 gassy environment. Please also give the details of the maximum or minimum levels for the parameters.

It’s simply not true. From pharmaceutical research to electronic circuit design, companies are moving to India, China, etc. as we speak.

They have to pay only a fraction to a medical researcher in India when compared to what they make here. And, unlike what many want to think, there is no significant decrease in the quality of the output –a Ph.D. in biochemistry from Delhi is as capable as an American graduate.
An entry-level researcher in biomedical technology in the USA starts with a salary of ,000 USD per year.

In India, the same starts with ,000 USD per year.
