As for ordinary resistors, the noise of photoresistors consists of thermal, shot and flicker noise; the thermal component dominates at frequencies above 10 kHz and brings a minor contribution at low frequencies.

Flicker noise is often characterized by the corner frequency " f " c between the region dominated by the low-frequency flicker noise and the higher-frequency " flat-band " noise.

The output of the device is again multiplied with the same carrier, so the previous information signal comes back to baseband, and flicker noise will be shifted to higher frequency, which can easily be filtered out.

The relatively new phenomena are, for instance, an " unpredictable " measurement progressive ( drift ) error, as well as a flicker noise, which is detected everywhere and cannot be suppressed by averaging the data.
16.
Flicker noise is found in DC, if the current is kept low, thermal noise will be the predominant effect in the resistor, and the type of resistor used may not affect noise levels, depending on the frequency window.

The articles and panel discussions is interesting in that they concur on the existence of the frequency flicker noise and the wish to achieve a common definition for short and long term stability ( even if the conference name only reflect the short-term stability intention ).

For DC measurements 1 / " f " noise can be particularly troublesome, as it is very significant at low frequencies, tending to infinity with integration / averaging at DC . At very low frequencies, you can think of the noise as becoming drift, although the mechanisms causing drift are usually distinct from flicker noise.
