Normalized 1/f noise at 1 Hz
Where
En(normal) = 1/f noise normalized to 1 Hz
en(flicker) = noise spectral density measured in the 1/f region
fo = the frequency at which the 1/f noise en(flicker) is measured
1/f total noise calculation
Where
En(flicker) = total RMS noise from flicker
En(normal) = 1/f noise normalized to 1Hz
fH = upper cutoff frequency or noise bandwidth
fL = lower cutoff frequency, normally set to 0.1Hz
