A question in my electric engineering class

    it's a question given in the sample exam

    I think for the first question, there is not much we can do to recover the function x(t), because it gets squared ...

    for the second part, sampling rate needs to be greater than 2*wm
    but then we dont really know what;s going on with the LTI (right before the input gets sampled), so I'm not sure if we can successfully predict the sampling rate for the second part either

    any suggestions?

    Thread moved to the homework forums.

    kolycholy, what can you tell us about sampling rates and aliasing?
