What did Sine wave tell to me (Electronics And Life - Part I)

I am an electronics engineer by qualification. What I have learnt technically, by completing a degree in electronics is highly debatable. But what electronics has taught me is, how to lead a meaningful life. I would now to let you know some of them.

What did the sine wave say to me...?

1.) Sine wave is the simplest waveform that can be generated naturally.

It says keep simple things simple. Donot get into the habit of Making Simple things Complex, which I generally call MSc degree.

Whatever is natural is simple and long lasting.

2.) When delta t is very small we can assume the wave to be smooth and increasing monotonically (from 0 to pi/4 and 3*pi/4 to pi) or monotonically decreasing in the other ranges. But when you consider the whole range it has both positve and negative slopes.

It says when we consider in small patches it may either appear as a string good times (or a string of bad times) but when you consider the whole life you will get to know that every trough is followed by a crest and every crest is followed by a trough.

So be humble when you are going upward and be optimistic when you are going down.

3.) Cos wave is a variation of a sine wave. It is just a sine wave with phase shift. It start with peak value at the beginning.

Some may start with a high and some may start with a low. But each one of us has got to go through highs and lows.

4.) Fourier wave says that any complex waveform can be broken down into 'n' sine waves ( as n increases the approximation also increases) of different frequencies and amplitudes which in turn gives rise to the complex waveform when they are superposed. )

Every complex and difficult task can be broken into a number of simple and easy tasks. But in real life the actual value should not increase towards infinity but it must be optimum. This is true up to a certain extent in electronics also. As n increases the approximations become more accurate.

But after a certain value the increase in accuracy in snot worth the extra time and efforts.

5.) The average output of a sine wave is zero. So just by increasing the amplitude or frequency you cant increase the total power output. The only way of increasing the average output power is by adding a positive offset.

Since you know you have to go through the highs and lows make your attitude independent of them. Your output {or success} is dependent upon the offset and that is nothing but the altitude. So increase your altitude in the positive direction.

Remember that your attitude decides your altitude. So develop an attitude where in you can handle the crests as easily as you handle the troughs.

Next in series : What did diode equation tell to me..?

sorry typo error "comparison"

Thanks nandhini. Well analogy would have been the right word i suppose.
