The multiplier-free design is obtained by finding power-of-2 coefficients and also quantizing the state variables to power-of-2 numbers. Expressions for the noise variance are derived for the quantized state vector and the output of the filter. A “structuretransformation matrix" is incorporated in these expressions. It is shown that quantization effects can be minimized by properly designing the structure-transformation matrix. Simulation results are very promising and illustrate the design algorithm.}, journal = {International Journal of Electronics and Communication Engineering}, volume = {3}, number = {11}, year = {2009}, pages = {1995 - 2001}, ee = {https://publications.waset.org/pdf/9903}, url = {https://publications.waset.org/vol/35}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 35, 2009}, }
