I tested the "LMS Norm" module by filtering a noise signal in matlab with 16 random, real coefficients, then running the input and output signal through the LMS norm module to see if it could determine the 16 coefficient values. It did not work, until I realized the produced coefficients seemed to be limited to the range +/-1. When I reduced my original coefficients to be in this range the LMS Norm module produced accurate estimates of each. If the module is a "floating point" module, why would its coefficient range be limited to +/- 1? There is no indication as such in the online help documentation. Perhaps I am using it incorrectly?
