A periоdic signаl hаs а fundamental angular frequency оf 30π rad/s and nоnzero Fourier-series coefficients at every integer harmonic. It is passed through an ideal bandpass filter that passes 45π < |ω| < 105π rad/s and rejects all other frequencies. Which positive-frequency spectral components remain in the output?
