Hi all
How exactly the tuned circuit of the the RF stage
in a digitally controlled radio reciver is controlled .
I understand that the local oscilator is based on a PLL , which is controlled by some micro controller .
My question is how the front end tuned circuit is tuned to
the relevant frequency which is local oscillator freq +/- IF freq ?
Thanks
