Nonstationarity: patching |

A common form of linearized **geophysical inverse theory** is

We choose the operator to be an identity and we rename the model to be signal . Define noise by the decomposition of data into signal plus noise, so . Finally, let us rename the weighting (and filtering) operations on the noise and on the signal. Thus the usual model fitting becomes a fitting for signal-noise separation:
