One of the disadvantages of DAB and DAB+ is that portable receivers
require a great deal more power to operate than analogue ones.

The same is true of televisions I gather. Proponents claim that this
is balanced by the relatively low power of the transmitters. I'm not
convinced, but that is their claim.

This is untrue of course.
There is less chippery in a modern digital set so they use less power.


One (less power) doesn't neccessarily follow from the other (less
chips). It depends on the nature of the chips, supply voltage,
operating frequency and I/O characteristics.
