Digital modes as DV use a confined portion of BW, less than BW required by SSB audio signal of relative high quality. Certainly is impossible the coexistence of DV signal with audio signal at same channel, including another DV signal, however several DV signals located one next to the other are perfectly decoded (into normal audio BW of 3.3 Khz can be three DV channels) but three audio signals located same manner become to non discernible signals.
