> (the joke is that analog computers don't have clocks... Do they?) Not a digital clock, no. But your modem controller (2.4GHz, 5GHz or whatever) has a frequency that the radio analog chips are adding, multiplying, exponenting and decimating to pull the data out of the radio waves. And computation to pull data out of (or push data into) a 2.4GHz channel is best done with analog today. Sure, SDR exists but its far more expensive than some PLLs and other analog techniques.
