Quantum hf Noise Primer

 

 

 

 

 

 

 

 

 

The quantum noise power in a 1 Hz bandwidth has a value given by:

hf = 3.03 x 10-19 Joules

 

The parameters in this classic formula have the following values:

h = Planck's constant (6.63 x 10-34 J.s)

f = frequency (4.57 x 1014 Hz) for a visible wavelength of 656 nm
