The firstexperiment uses LMS algorithm for an application of system identification. Theunknown system can be any types of plants. Here we use an FIR filter (thelowpass filter from Chapter 5) as the unknown system. We will show you how theadaptive filter adjusts its weights to match the unknown system. The secondexperiment is an application of adaptive linear predictor. It can be used toseparate the narrow band signal from wide band signal. It can also be used toremove a narrow band signal from the wide band signal as a notch filer.
