Abstract

The Burg algorithm for maximum entropy power spectral density estimation is applied to a time series of data obtained from a Michelson interferometer and compared with a standard fast Fourier transform (FFT) estimate for resolution capability. The propane transmittance spectrum was estimated by use of the FFT with a 218-data sample interferogram, giving a maximum unapodized resolution of 0.06 cm−1. This estimate was then interpolated by zero filling an additional 218 points, and the final resolution was taken to be 0.06 cm−1. Comparison of the maximum entropy method (MEM) estimate with the FFT was made over a 45-cm−1 region of the spectrum for several increasing record lengths of interferogram data beginning at 210. It is found that over this region of 45 cm−1, the MEM estimate with 216 data samples is in close agreement with the FFT estimate using 218 samples.
