Building AM waves

129

I learned long time ago....

When a carrier (100KHz) is modulated by a signal (5KHz),
an upper side band (105KHz) and a lower side band (95KHz) will appear.

I had known it only logically. Now, when I tried to mix the carrier and upper side and lower side two bands, I could see a typical AM wave form.

Then I again knew the AM wave is just only including 3 parts, a carrier, an upper side band, and a lower side band. It dosen't include any other frequency waves. Is it too late that I found it...?

Here is a low-end reciever without proper demodulation but works as a low cost soln http://everycircuit.com/circuit/5095971756703744

To abobaker, thank you, for demodurating. Crystal radio (^^), germanium radio (^^) (^^). So, your filter made of only C and R may be the least composition.

U R welcome .. Hurz modified it a bit into a much better one if you want to take a look
