I am having trouble finding a good resource for understanding the design of a very basic AM modulator circuit.
Specifically, I am using a simulation tool which provides an AM wave, which consists signal frequency and a carrier frequency. It produces a nice AM looking signal.
I am trying to create that signal from more basic components, but I cannot find any working schematics.
I am using a handy simulator found here: http://www.falstad.com/circuit/circuitjs.html
In my case, I am using a 40Hz signal on a 300Hz carrier. The AM element is configured the same way.
My 300Hz element is AC, -2.5V <-> 2.5V. My 40Hz element has a base voltage, so it goes between 0 -> 5V.
I'm pretty sure I'm missing a lot, but can someone help me fill in the blanks?
