Name: IIR Filtering: Filter-Coefficient Quantization Exercise in MATLAB
ID: m10813
Language: English (en)
Summary: You will design a fourth-order notch filter and investigate the effects of filter-coefficient quantization. You will compare the response of the filter having unquantized coefficients with that of a filter having coefficients quantized as a single, fourth-order stage and with that of a filter having coefficients quantized as a cascade of two, second-order stages.
