WebDec 16, 2024 · 1 Answer Sorted by: 0 Yes, the method you have used generates an AR- (1) random process by inputting Gaussian white noise of unit variance into the LTI filter defined by the coefficeints a and b. Then you are adding some uncorrelated noise to it, which means your random process is not anymore a pure AR- (1) but a noisy one. Share WebFeb 20, 2014 · Show older comments. Mario on 20 Feb 2014.
