So the H1 and H2 frequency response estimators for SISO systems are defined according to: H1 = Pyx Pxx H2 = Pyy Pxy. Where A B is an element-wise division of vectors A and B. The H1 estimator should be used when the noise is uncorrelated with the input, and H2 should be used when the noise is uncorrelated with the output. systems theory and family therapy
