What does it want?

This might be my third question, ever. My emphasis in college was Linear Algebra, not this.

Playing with Fourier Transforms.

Start with an input function: [math]A\cdot e^{j\phi}\cdot e^{2\pi j \omega}[/math]
"A" and [math]\phi[/math] are constants.
[math]\omega[/math] is the normalized frequency

At what frequency will the output be zero (0)? It can't just be [math]\dfrac{\phi}{2\pi}[/math]? That might flatten things out on the way in, but zero (0) output?

Do I get to search for a frequency that actually makes the output function self-destruct? Emotionally, I find that hard to comprehend. What does it want?

Speculate?

Will the output of ... what ... be zero?

Your input function seems to be lacking a time variable. Is that a typo or am I completely misunderstanding the question.

You have asked the right question of me. I found my time variable and I see that I must find [math]-\pi \lt \omega \lt \pi[/math] that makes the response function zero. Very good.

What does it want? Love and attention from a Physicist. Just like any other Physics problem.

(I feel proprietary about Fourier Series problems.)
