Doing a search in quora about Why does Amplitude Modulation have sideband frequencies? i found an answer and within it, a user answered with the following statement:
"When you try mixing two signals, there will be something know as harmonics that will occur. This means that frqncy X (+) Frqncy Y will not just form frequency Z but some more frequencies that will be embedded into the system."
Can someone clarify and or exemplify the statement?
