design versus trouble shooting
Design from the back to the front. Then trouble shoot the probem from the front to the back. Simple attack method I use.

Re: Troubleshooting approaches.
->One is to start with the symptom and anlalyze it while gradually moving up

I wonder whether it is possible that more detail is described as adding a specific s/w tool, actual method analytical graphic or flowchart used in the project.

amplifiers performance
"The performance of some amplifiers degrades when supply voltages get too big or small, so check the supply voltages against those shown in the data sheet."

 

This is really a common issue when working with amplifiers, the supply voltage value and driving capability of the feed lines in terms of rise time, and fall time is really an aspect you would not consider at all if you have a theoretical knowledge of amplifiers but it's a pratical issue to be solved.

Re: Troubleshooting approaches.
@tzubair: IMO I feel many companies are not willing to take the next step and go ahead by taking a risk. Many are focusing on short term goals right now to stay in the market which is wrong

Re: Troubleshooting approaches.
"Our main goal here is to determine why something does not work as expected and find out any possible solutions for that problem."

@Netcrawl: I think for this reason many companies lay so much emphasis on quality control techniques like TQM or Six Sigma. That takes care of the fact that you don't fix the problems, you fix the causes of the problem and lead your system to be of a higher quality in the long-run.

Re: Troubleshooting approaches.
Good point @tzubair, troubleshooting is a systematic approach in solving or fixing specific problem, the first step in troubleshooting is to describe and understand the problem completely. We need to know where to start and what causes the problem. Determining where the problem really originates is not an easy task but its one of the most important things in solving problem. Our main goal here is to determine why something does not work as expected and find out any possible solutions for that problem.

Troubleshooting approaches.
"Troubleshooting is a methodical approach to finding a problem, but there's also an art to it. Looking for trouble in all the wrong places eventually leads you to the right place!"

From my experience as a support engineer in the software world, there are two approaches that you can take while troubleshooting a software. One is to start with the symptom and analyze it while gradually moving up. The other is to have a holistic approach where you test everything regardless of where the symptom is occuring. While the latter takes a lot of time and effort, it is more effective in the long run as it also takes care of potential issues that may have risen in the future.

Most of us know about the latest Rover to land on the Red planet called Mars—Curiosity. But did you know that since January 2004 NASA’s Mars Rover called Opportunity has traversed the Martian landscape a distance of 26.661 miles, just a little more than the distance of a full marathon run.
Planet Analog had the following Q&A with Dave Robertson from Analog Devices regarding Moore’s Law as the April 19 50th anniversary approaches.
Moore’s Law will celebrate its 50th anniversary on April 19, 2015. Many say that the statement or theory has run its course due to the next moves toward 450 mm size wafers, extreme ultraviolet lithography (EUV) and 20 nm CMOS.
When your home’s deep freezer, full of food, experiences an AC power failure while you are out for an extended time, its contents can thaw out. If the AC power is then restored before you return home, the contents can re-freeze and you may never know that your food is spoiled. This has given rise over the years to a number of freezer-alarm circuits and methods to detect thaw and re-freeze.
It seems like we just had LTE and LTE Advanced beginning deployment in base stations everywhere. In spite of that effort, there has been heavy discussion of early development ideas of the 5G next-gen architecture to meet the ever-growing demands of the cellular airwave capacity, speed and customer future needs.
