Abstract

A computer code for a 1/f noise generator has been developed and is used to produce long sequences of temporal 1/f noise. This generator, which was developed in 1971, avoids the large memory requirements associated with other methods that have been used to produce extended records of 1/f noise. The power spectral density (PSD) of a sequence of such noise is calculated to verify its 1/f character. Noise that has a PSD of the form 1/f^(alpha ), where (alpha) is a non-integer exponent, may also be generated. As an example, the temporal 1/f noise current from MWIR HgCdTe photodetectors is simulated.
