Hi,
TVRX IF frequency is fixed at 44MHz, But the RFX400 IF frequency is 3MHz or 4MHz, so DDC is -3MHz or -4MHz. What is the reason does not use the fixed IF frequency? I think which is not fixed seems to be a bit complicated. I wonder why different IF frequency is necessary such as 3or 4MHz. Is it the constraint because of the hardware? can some help me with this problem? thanks in advance Sang-won -------------------------------------------------------------------------- Sang-Won Kim @Cognitive Radio Research Team Tel : +82-42-860-4850 Fax : +82-42-860-5199 email : <mailto:[EMAIL PROTECTED]> [EMAIL PROTECTED]
