Abstract:

This report gives an account of a short experimental study of the noise power spectrum of lowtemperature indium antimonide photoconductive cells within the frequency range 20 c to 5 kc. The results from 10 cells showed that the noise power spectrum was of the form P varies as 1f to the nth power below a certain frequency f sub b and a constant value above this frequency. Values for n and f sub b are presented. It was found that variation of the polarizing current through the cell changed the magnitude but did not alter the shape of the power spectrum, but that a microphonic effect which was induced by faulty cooling produced a marked increase in the value of n.
