My Professor is unavailable, and there is no TA. i know the basics of wave propagation but i just don't understand how to perform the summation. Following your steps i get: $u(x,t)=\sum\limits_{\omega =20\pi }^{400\pi }{[A(\omega )~{{e}^{i(\omega t)}}+B(\omega )~{{e}^{i(5k-\omega t)}}}]\,\,$

Ok, i think i got part A: In order to conserve all the frequencies, there must be at least 2 samples per 1 wave length. so the spatial Nyquist is then: ${{k}_{\max }}=\frac{1}{2\Delta x}=0.1$ and on the other hand: $k=f/v\to {{k}_{\max }}=200/330\sim 0.6$ so we won't get all the energy...

Thank you Thank you, but I'm not sure that i can use the given information in part b for calculations in part a ... and as for part b, how can i get anything about the amplitude ?

Thank you! but... How did you compute the Nyquist frequency in this ? In order to calculate the Nyquist frequency i need the sampling time interval of the receivers no ?

Thank you! but... You are right, i calculated the phase change between the receivers, i got 66 [Hz]. but how this affects the summation ?

Homework Statement Two receivers, d=5 [meters] apart, are recording an air wave signal. The air wave travels in v=330 [m/sec] and coming from one side of the receivers. The air wave contains all the frequencies between 10 [Hz] and 200 [Hz]. a) If we sum up the recorded signal from the...
