I understand that mixers are used to convert a signal from one frequency to another, but why would we want to do this?
If the signal needs to be transmitted at a certain frequency then why not just use amplitude modulation or frequency modulation to put that signal onto a carrier signal of that certain frequency, isn't that how it's normally done?
Thanks
