<math>\bullet x(t)</math> does not need to be band limited when modulated with a complex exponential in order for the demodulator to produce <math>\ x(t)</math>.

<math>\bullet</math> If the signal is not band limited and modulated with a sinusoidal carrier the copies will always overlap. That is <math>\ \omega_{c} - \omega_{m} < 0 </math> beacuase <math>\omega_{m} = \infty </math>
