So the amount of photons-per-second should be double the frequency of the carrier-wave? In my first post of the thread, I stated that the carrier frequency for the AM signal is 150 KHz. Each photon in that signal is 150 KHz. It's possible to have one 150 KHz photon, right? My question was relating the modulator wave. If I have using 150 KHz photons for my carrier-wave on AM radio, what is the minimum amount of photons-per-second I would require to transmit, a modulator-signal [through the 150 KHz carrier-signal] of 20 KHz? I am guessing 40,000 150-KHz-photons-per-seconds. Am I right? No. For AM with a 150 Khz carrier and a steady 20 Khz tone, you have to emit 1 130 Khz photon, 2 150 Khz photons, and 1 170 Khz photon approximately every 12 microseconds. -- Jim Pennino Remove .spam.sux to reply. |
