    Silicon Laboratories makes several receiver chips that do the complete demodulation with very few external parts. They are SMD parts so a breakout board is very handy. Sparkfun carries some, I have one from a few years back that does AM & FM but they seem to have discontinued these.

    The control is digital so a micro controller is also required, but by the end still simpler then trying to build one from scratch.

    Analog receivers are not a beginners project, and probably require special test equipment to get tweaked in.

    Building an AM/FM radio from scratch is not easy for a beginner, especially one who does not know where to start, but you may learn a lot (if you don't give up first). If you build one based around a chip you have a much better chance of success but you will not learn very much because everything is done by the chip.

    Perhaps you could start by building a simple AM radio from scratch and then see how you feel about attempting an FM radio.

    Do you want to build a functional AM/FM radio or are you simply experimenting in order to learn about radios?

    Why not start of with a simple AM crystal radio?

    You cannot get any simpler than this:

    It is one or the other, not both.
    Did you see my post?

    An AM/FM radio is not simple.

    If you want to build an AM radio in stages from scratch then start with the circuit I showed you. It uses only four components.

    If you google "AM radio schematic" you will find many designs of varying complexity so choose one you like (come back here and get an opinion if you're not sure), buy the components, and get soldering ; I don't understand what more you want.

    Thank you I Already chose a schematic 1 - MK484 for AM Radio 2-TDA7000 for FM Radio and I will try
