simulate this circuit – Schematic created using CircuitLab
I need to design an am receiver as a project. On the front end I have three modules; BPF1 the "roofing filter" or the "pre-select filter", BPF2 to further "protect" the demodulator, and an RF amplifier between these two filters. Should my filters be passive or active?
The block diagram above shows what I am designing.
