Yes, the "original" IF bandwidth of, say 96 khz is changed to +48 khz (real) .... 0 khz .... and "minus" 48 khz. I simply write "minus" here, the correct notation would be something "complex" 48 khz. And then put a label 0-96 Khz on it again :-) I am now yet 100% sure.
Still looking for a receiver design that receives more that one tv-video carrier with low bandwidth (<500 Hz).
