First off, I wish to say that I am not exactly an expert in electronics. Though I do consider myself to have a basic knowledge.
I'm finding that I can't seem to understand what AM truly is.
I was thinking about how I would go about possibly making a very basic AM transmitter at home (I'm talking very short range as I would hate to do anything unlawfully).
My basic (and probably stupid/impossible?) design was using an alternator to produce a high frequency carrier wave. I would then use a microphone which varied resistance, like a carbon microphone, with sound. I would pass the carrier wave directly through the microphone and the varied resistance would, so to speak, alter the amplitude of the carrier wave produced by the alternator.
Now, if I sent this wave out a few metres and used a receiver which rectified the carrier wave and smoothed the result with a capacitor, would I gain any intelligible data from it?
I think I understand that what I just described is not what people would consider AM. But then what is AM?
Thanks in advance!
