Abstract:

We propose a new methodology to reduce the widths of spectral lines. This procedure, which is performed entirely in the time domain, combines elements of the methods of Fourier Self-Deconvolution (FSD), Maximum Entropy (MEM), and Linear Prediction (LP) in such a way as to take advantage of the efficacies of each of these procedures. The procedure is illustrated with examples.
