Do we have the technology to do this?
Here in UK , like probably elsewhere in the world, FM stations need to be
seperated 200Khz to avoid mutual inteference. A good RX ought with good IF filtering ought to be able to seperate two 200 Khz spaced FM signals I think. But of course stations are only 100Khz apart so it nigh on impossible to seperate stations under these conditions as far as I know. Well, if filtering won't sort out the problem, can you seperate the stations any other way? Can you make a circuit that responds only to the wanted station when it is just fractionally stronger than the unwanted station? That's the only thing I can think of, apart from antenna solutions. Do we have technology these days to do what we thought was impossible in this case? |
