Quantization Errors A real number can be represented in two’s complement form with B + 1 bits as Q ( x ) = x m p - b 0 + B s i =1 b i z - i P Quantization will effect the location of the poles and zeros. Only a finite number of pole locations can be implemented with quantizaed coefficients. Summary 12 – p. 2/ 4

Unformatted text preview: same filter may provide different behavior in the presence of quantization errors. The representation form affects the location of possible poles. Cascade form is more robust in the presence of coefficient quantization. Limit-Cycles: Oscillations in recursive systems due to nonlinearity (finite-precision arithmetic) even when the input is zero.
