## Main Question or Discussion Point

To find the frequency, Why do you need to consider the signal over long period of time?

For example - if you look at a sine wave from 0-360 with two cycles, isn't it enough to get the frequency?

I get the second part - you need a short time window to see sudden changes in frequency.
