  • $\begingroup$ Yeah I realized I needed to review taking the inner product of complex vectors. So is it that the input signal gets treated like a complex vector where every element has the 0i component? If this is the case then if I'm using MATLAB to take the inner product of the test signal and a Kth complex sinusoid, would it look something like dot(complex_sinusoid, test_sig)? $\endgroup$ Commented Apr 29, 2016 at 4:16
  • $\begingroup$ @TSIguy Your code above looks fine... modulo a couple of quibbles I have; see my update. $\endgroup$ Commented Apr 29, 2016 at 11:46
  • $\begingroup$ generate_sine taes in a frequency in Hz, phase offset, amplitude value, sampling frequency, and signal length all respectively. Also I originally tried your suggestion of negating the complex part, but I wasn't sure if the dot() function automatically takes the conjugate of a complex vector. I've since switched some things around and now I get the proper results. Thanks! $\endgroup$ Commented Apr 29, 2016 at 17:20
