A Note on Covariance-Invariant Digital Filter Design and Autoregressive Moving Average Spectrum Analysis.
Abstract
Consider an autoregressive-moving average (ARMA) discrete-time sequence (x sub k) with covariance sequence (R sub k). The results are derived and presented somewhat differently than usual to complement the results for the synthesis of covariance-invariant digital filters. In the context of spectrum analysis, the results provide a means of performing ARMA spectrum analysis on data that arise as sampled data from a rational continuous-time process. An important result, shows that the ARMA spectrum can be obtained without actually solving the nonlinear factorization problem for the MA coefficients.
