Default Minimum photons-per-second [amplitude] required for 150 KHz?

Hi:

What is the minimum amount of photons-per-second needed for a 150 KHz
AM radio carrier wave to transmit audio signals? Around 20,000-photons-
per-second?


Thanks,

Radium


The same as the minimum number of data bits required to represent this
signal. The number of photons/data bits will vary depending on the
complexity, frequency and depth of modulation of the carrier wave.
