Use MATLAB routine sig noise to generate two arrays, one 128 points long and the other 512 points long. Include 2 closely spaced sinusoids having frequencies of 320 and 340-Hz with an SNR of −12 dB. The MATLAB call should be: x=sig_noise([320 340],-12,N); where N=either 128 or 512. Calculate and plot the (unaveraged) power spectrum. How does data length affect the spectra
