In this brief, a two-stage approach for the design of 1-D stable variable fractional delay infinite-impulse response (IIR) digital filters is proposed. ...
In the first stage, a set of fixed delay stable IIR filters are designed by minimizing a quadratic objective function, which is defined by integrating error criterion with IIR filter stability constraint ...
For the purpose of reducing the computational complexity for the design of variable digital filters, a two-stage approach, i.e., designing a set of fixed-coefficient filters, and then fitting each of the ...
