This is a soft question . In the walk-in for the lectureship, I have decided to give demo lecture on the topic of Fourier transform.
The principal of the institution ask me to take lecture interactively with students on the given topic for around 20 to 25 minutes. I should teach them interactively by which they can learn Fourier transform with interest.
But I could not dare to counter question him "How to make and teach Fourier transform topic interactive one making use of given time span?" ;-)
Now,I am confused with what should be the start of the lecture? Should I take any example or any application than directly coming on equations or any other ?
What should I tell about importance of Fourier transform? The important factors of signals I.e. phase,frequency and amplitude ? So can anybody help me for it?
