Just to share some information I found that gave me some light about the purpose of the diode: https://www.edn.com/increase-piezoelectric-transducer-acoustic-output-with-a-simple-circuit/ This is for an acoustic transducer, but might be the reason the Elenco engineers included the diode. And I...

I just want to say thank you to all the participants who have given me very valuable information. Thank you so much for sharing your knowledge with me. Blessings!

I will take your advice. Thank you so much.

Thank you so much for sharing. You're very kind.

Thank you so much for your answer.

Thank you so much for the helpful advice.

OK, so it seems two phenomena happen in the system: we have RF oscillations and AF amplication happening at the same time, which could not be explain by conventional block diagrams of AM systems. So if I use this system in a technology class for middle school students to have them to explore AM...

Well, that's exactly the information I'm looking for. I'm asking if someone can explain to me how this system works since it is not explained in the documentation :cry:

Snap Circuits Manual https://www.elenco.com/wp-content/uploads/2017/10/753098-2.pdf Projects 122 and 213 This is the kit https://www.google.com.pa/url?sa=t&...p/B0000683A4&usg=AOvVaw1XqTGc7s8KYSWapKVfLp3r

You can see the system working in the following video. The audio is in Spanish but it shows the system working.

Hi, guys! Could anyone provide an explanation about how the following AM transmitter works? It is similar to the AM transmitter for project 122 of the Snap Circuit kit by Elenco. Does it work as a switching modulator?

Thank you so much for your help!

so according to what you have exposed, there is no geometrical interpretation for multiplying a vector (with real numbers as components) by a complex number? performing that kind of operation won't make the vector to have an expanded magnitude, to rotate, or something else?

thank you so much for your quick responses, guys! you have been very helpful.
