I'm supposed to design and build the intermediate frequency amplifier portion of an am receiver.
I've been looking around online and correct me if I'm wrong but the intermediate frequency amplifier takes an ac signal, filters it, amplifies it, and then goes through that whole process 1 to 2 more times. After looking at some sample circuit designs online it seems that a lot of them use transformers. Is it really necessary to use a transformer? Couldn't I just build a band pass filter and hook that up with a transistor acting as an amplifier?
