I had an exam today about discrete fourier transforms and stuff but I didn't understand a question
I've been asked to give a function x[n] that is imaginary and odd and draw a graph of it
Would x[n] = i*sin(nT) be a correct answer?
And then simply draw a sine function like I would have if it was simply x[n] = sin(nT) ?
It can't be that simple can it?

x[n]=x[n]

OP tell me what is the inverse Fourier transform of the constant function [math]\mathbf{1}[/math] on the frequency domain [math]\{0,1,2, \dots, N\}[/math]?

delta[n]

I feel like I'm not getting all the information here. Do you remember the question exactly? Did you write it down? It seems like some or what it was asking for was implicit in the context of the other questions
