11.23 Parallel Connection of IIR Filters—MATLAB Use MATLAB to design a Butterworth second-order low-pass discrete filter with half-power frequency θhp = π/2 and a dc gain of 1; call it H(z). Use this filter as a prototype to obtain a filter composed of a parallel combination of the...
FIG. 2 shows the frequency response of an IIR filter employed by a specific embodiment of the invention. After the oximetry data has been filtered, it is processed by a saturation calculation algorithm (box 50). According to a preferred embodiment of the invention depicted in FIG. 1a, two ...

The new adaptive IIR filter realization has lower computational complexity than the standard parallel realization. A discussion regarding their properties and convergence speed is also included. In order to illustrate the performance improvements, some simulations results are included in the system ...
In a sense the function of the prefilter is performed by the parallel sections themselves without using a prefilter. In addition, the use of a variable convergence factor in the Gauss-Newton algorithm is investigated. Extensive experimental results show that the proposed realization leads to ...
