In all the direct-conversion architectures I am facing there is the presence of I and Q carriers.
Razavi in his book RF Microelectronics states that for zero IF receivers, the BB signal may have a chance of self-corruption. So, in order to alleviate this problem the signal is downconverted to in-phase and quadrature-phase and the signal will not be corrupted.
Please help me understand this vital point...
