In single sideband modulation, we filter out the lower or the upper band to separate out these signals as if they were two independent signals. Each half is enough to recover the signal. Filter 1 and Filter 2 in Figure 7 do just that and show how we could transmit two signals in the place of one.

WebFilter method. The filter method of SSB generation produces suppressed carrier double sideband signals (using a balanced modulator), one of which is then filtered to leave USB or LSB. This can be achieved using one of two methods. The first uses two filters that have different passband centre frequencies for USB and LSB respectively. WebA review of the Drake TR-4 series filter scheme. First is uses a 9.0 MHZ system, very common in those days.
