Advanced Techniques for Black Box Modeling (Effect of Signal Quantization; Multirate Sampling of Wideband Systems).

Abstract : The pencil-of-function method is a black box modeling method. The research described here deals with the issues of (1) effect of quantized input output signals and (2) the modeling of wideband systems. The development shows that the pencil-of-functions method together with certain statistical corrections and/or the use of multirate sampling lead to enhanced transfer function models. Also, it is shown that LF, MF and HF test results, when employed in conjunction with procedure described for adjoining smallband transfer functions, yield successful wideband identification. (Author)
