Intermediate Frequency
Hello,
I want to know the importance of intermediate frequency in any receivers. IF was used in Superhet transceivers. My question is why doesn't anyone use zero IF now a days. What is the problem of brining the RF signal directly to baseband? Does the IF stage conditions the incoming signal? What are the advantages of the IF stage? Just confused. Can anyone throw some light on this? Thanks. |
