Sure, but that's on the receiver side for carrier recovery. Wouldn't it be problematic if you mashed a bunch of channels/allocations sufficiently close together that they started wandering on top of each other?
- PoachedSausage 9y agoModern DAB/DVB receivers are usually zero-IF, the wanted band of frequencies is mixed down to baseband and filtered with a sharp cutoff Surface Acoustic Wave filter then sampled with a fast ADC. Selectivity is then dependent on DSP. On the transmit side, you have to carefully combine the outputs of your various transmitters with a complex filter network, which at high powers looks something like: http://admin.mb21.co.uk/tx/userimages/8448proc20120403120238.jpg http://admin.mb21.co.uk/tx/userimages/8448proc20120403120238...
