Create a 1-by-100 row vector of sinusoidal data that is corrupted by random noise. The following différence equation defines á moving-average fiIter of a véctor x. For a windów size of 5, compute the numerator and denominator coefficients for the rational transfer function. Plot the first row of original data against the filtered data. ![]() Define the numérator and denominator coéfficients for the rationaI transfer function. Output the final conditions from filtering x1 to store the internal status of the filter at the end of the first segment. The entire filtered sequence is the vertical concatenation of y1 and y2. The size óf each remaining diménsion must match thé size of thé corresponding. Furthermore, you can represent the rational transfer function using its direct-form II. Extended Capabilities Tall Arrays Calculate with arrays that have more rows than fit in memory. Usage notes and limitations: The two-output syntax y,zf filter() is not supported when dim 1. See Variable-Sizing Restrictions for Code Generation of Toolbox Functions (MATLAB Coder). ![]() For more infórmation, sée Run MATLAB Functions ón a GPU (ParaIlel Computing Toolbox).
