It wouldn't be. That's the reason for the filter.

Consider the bandwidth of one against the other and you have your answer.
Continuous Wave is not modulated, thus it is a narrower signal. OTH, SSB
is modulated and has a wider bandwidth. An Amplitude Modulated signal
would be twice as wide as the SSB signal.
