Day 4 !

In the last four years of engineering every conceivable problem on planet earth could be explained with

1. Noise.
2. High/low frequency spikes/transients.
3. Bandwidth/data rate/transistor switching speed
4. Line delay
5. Line of sight
6. EMI/RFI
7. Power factor

Among these 7 points each and every problem, regardless of the subject could be explained. In worse cases a scenario like:

Examiner: So, when you do have a limitation on the switching speed of the IGBT, why don't you use MOSFETs that switch at a much higher speed. While the answer should have stayed clear of point 5, you do come up with smart arse answers like "Sir, could it be because of line of sight?"

And then we wonder why those examiners give us the "you're not fit to be engineers looks!"

However, when this young lady tells me "I want to declare 100 variables and not use an array because I don't like for loops and I'm more comfortable.... blah blah" I wish I could tell her, "And if you do, there would be high frequency spikes that would interfere with the signal and increase the RFI making it necessary for you to use bulky filters and power factor correction!" And then with sadistic pleasure watch the expression on her face.
