摘 要: 提出一种基于线性四阶齐次理论改进的新型四阶海明(Hamming)窗,它将三角函数的序列进行线性四阶组合,并对其幅度条件进行线性归一化,获得一种可调节参数的新型四阶窗函数,从而得到一种新的算法以提高滤波器的设计精度,满足严格的滤波条件。最后借助Matlab软件对本设计进行对比分析及计算验证,证明了新型四阶海明窗的设计价值性。
关 键 词: 信息处理技术;有限脉冲响应数字滤波器;新型四阶海明窗设计;线性四阶齐次理论;设计精度

Abstract: The article put forward a new improved fourth-order Hamming window design based on fourth-order homogeneouslineartheory.It wasa linear combination of trigonometric function sequence with thenormalization of conditions for linear amplitude to obtain the fourth-order window function with a new type adjustable parameter, then a new algorithm to modifythedesign precision of the filter was obtained for meetingthe requirement of stringent filter conditions.Finally, a comparison analysis and calculation for this design using Matlab software proved the value of the new fourth-order Hamming window design.
Key words: information processing technology; finite impulse response digital filte; a new fourth-order of Hamming window design; fourth-order homogeneous linear theory; design precision
