【Abstract】 The amplitude response H r(ω) of the Ⅲ type linear phase FIR filter is optimized using the neural networks based on the sine basis functions,and the pulse response h(n) is acquired by weights c n.The simulation cases indicate the effectiveness and superior performance of the algorithm.更多还原
