Discrete Time Subharmonic Modelling and Analysis Part 2. Frequency Domain Analysis

In Part 1 of this paper (Li and Billings, 2004, a new method of constructing MISO NARX models was introduced for a class of severely nonlinear systems that exhibit subharmonics. In this, the second part, the frequency domain properties based on the results of the time domain MISO modelling in Part 1 are revealed, explained and discussed.....
