alkej-464	Muhsin, Noor K.	إزالة ضوضاءِ التي تَستعملُ أقلّ تكراريةً الخوارزمياتِ المربّعةِ	2011	9	.pdf	application/pdf	3510	183	67	As illustrated in section 3.1 and table 1 the FIR filter order (5) while IIR filter order (10) because FIR filter output is calculated using the current and past input, but not previous values of the output and produce more placental results at the selected order but IIR filters are recursive filters that use the surrounding input and previous output values together and the selected order introduce good results. To compare between the standard deviation of the two outputs the results shown that std of FIR output of HFN is approximately similar to std of the desired signal and less than of IIR output std but approximately similar to std of desired signal that mean that the deviation of the results from the true curve is smaller in case of FIR filters to remove both noises than the IIR filters.	cache/alkej-464.pdf	txt/alkej-464.txt
