hi guys

going a bit blank now....

been thinking a bit too much about time and frequency domain to a point where i've confused myself a bit...

The well known function: f(t) = sin(wt)

It is evident that this expression is in the time domain - but how can we get a frequency component, w , in this expression!!!!! really wierd !!

I know w is a constant (defined as the fundemental frequency) but aren't we sort of mixing time and frequency - which i hear is a bad idea!!!

Think about: If i ask what is the highest frequency component in f(t)=sin(200t), the answer would be 200 rad/sec. This is determined by merely looking at the expression in the time!!! But normally to determine the highest frequency component (or any frequency component) of a functino in time - we need to FIRST convert to the frequency domain!!!!!!

Do you guys see my issue here!!!

If anyone can attempt to shed light on the situation, my appreciation would be much like that of an impulse function: unbounded.

Thanks

John
